GRIPEN FLIES AFTER 12 MONTH GROUNDING
defenceWeb



Months of uncertainty ended on Monday (5 September) for the SA Air Force's (SAAF's) front line combat fleet when a single-seat Gripen C (tail number 3918) took off from Air Force Base (AFB) Makhado in the wake of "intense work by 2 Squadron technicians and pilots".

Details of the sortie - the first by a SAAF Gripen in a year - have not been made official with African Defence Review (ADR) director Darren Olivier saying 3918's return to the skies followed "final signing of a delayed support contract" and the sweat equity put in by 2 Squadron personnel. He called it "a remarkable achievement", given the timescales and resources available. Further evidence the single-engined jet fighter's take-off was truly a team effort came via the involvement of former 2 Squadron personnel volunteering reserve duty to assist.

Right now, Olivier maintains it's about regaining basic operational currency and will be "months" before combat readiness is restored.

"Even then it won't be to previous levels absent an increase in funding. There is still a long way to go," he said, adding 3918's take-off and subsequent landing was "an important symbolic step".

"At one stage it wasn't at all certain we'd ever see a SAAF Gripen in the air again."

The ever-present spectre of funds, more specifically the lack thereof, means the newly concluded support contract covers only 13 aircraft. This Olivier sees as sufficient to rebuild air combat capability, retain scarce skills and provide "some operational deployability". The three year contract is, according to him, important for stability and rebuilding capability. The capability side goes further than 2 Squadron and its air and ground crews. Forward air controllers (FACs) and other musterings rely on 2 Squadron for currency and qualification.

On paper the SAAF has a Gripen strength of 26, but one was damaged beyond economic repair and 12 will be mothballed to stay under the budget ceiling, leaving 13 aircraft operational.

There is talk of putting the Gripen into the air above AFB Waterkloof during the 21 to 25 September Africa Aerospace and Defence (AAD) exhibition.

Late last month Armscor told Parliament's Portfolio Committee on Defence and Military Veterans (PCDMV) that all SAAF aircraft maintenance contracts were resolved, with 40-odd contracts in place, including the Gripen and Pilatus fleets as well as the VIP aircraft.

In February this year, only 25% of SAAF aircraft were serviceable with Armscor at the time evaluating bids for aircraft support contracts.

GAMA STATEMENT ON FAA APPROVAL OF GAMI UNLEADED AVGAS STCS



General Aviation Manufacturers Association (GAMA) President and CEO, Pete Bunce, issued the following statement regarding the FAA's approval of Supplemental Type Certificates (STC) to allow General Aviation Modifications Inc.'s (GAMI) 100-octane unleaded fuel (G100UL) to be used in every general spark-ignition engine and every airframe powered by those engines.

"As we continue to work towards a safe and reliable transition to an unleaded future state for piston-engine aircraft, FAA issuance of a broader STC for GAMI's G100UL is a significant milestone. Manufacturers look forward to having an opportunity to understand the composition and performance of this new fuel to support commercialisation and use as a viable replacement for 100LL."

The type certification process and issuance of the STCs means the FAA has found that engines and aircraft operating on the new G100UL fuel continue to be compliant with the applicable airworthiness safety standard requirements such as Part 33 for engines and Part 23 for airplanes. Manufacturers understanding of a new fuel is essential to continued operational safety regulatory responsibilities and business activities such as customer technical support, warranty services and consideration of incorporating the new fuel in manufacturer issued service and approval documents and new production engines and aircraft.

As a stakeholder in the Eliminate Aviation Gasoline Lead Emissions (EAGLE) initiative, GAMA supports the general aviation industry's ultimate goal of a practical unleaded avgas that can replace 100LL and will continue to support Afton/Phillips66 and Lyondell/VP-Racing advancing through the EAGLE fleet authorisation testing & evaluation process and supporting deployment of Swift Fuels and GAMI working through the FAA STC certification process.



CUBCRAFTERS DEBUTS NEW ENGINE FOR EXPERIMENTAL CARBON CUB AIRCRAFT



First introduced in 2009, the original Carbon Cub had a power to weight ratio vastly superior to any previous backcountry airplane in its class. This was in large part due to an innovative new light weight 180 HP engine, the CC340 that was developed at CubCrafters. The power of that engine, in a sub-1000 lb. backcountry airplane, gave pilots the previously unheard-of short take-off and landing (STOL) performance that changed an industry and made CubCrafters a household name in aviation circles.

For the CC340, CubCrafters started with a standard Lycoming 0-320 engine chassis, but reduced the weight of the engine by more than 50 lbs. while also increasing its output from 150 to 180 horsepower. That new engine proved to be game changing for an entire class of light STOL capable aircraft in the backcountry. It allowed pilots to pioneer new landing areas and go places that were shorter and smaller than ever before. Now copied by many other aircraft OEMs for its outstanding dependability and simplicity, the CC340 has been a proven winner in the market since first introduced by CubCrafters more than a decade ago.

The original CC340 features a fixed pitch propeller, is carburetted, and has a high compression ratio to boost its horsepower. While innovative for its time, CubCrafters recognised there was still room for improvement with the CC340, and is now introducing a new lightweight engine for the Carbon Cub. The new engine is a fixed pitch version of the larger displacement 186 HP fuel injected constant speed prop engine first introduced by CubCrafters in 2017.

Called the CC363i F/P, this new engine offers several advantages over the CC340. It is fuel injected instead of carburetted, which allows for simpler operation overall and eliminates the safety concern of carburettor ice during low power operations. In addition, the fuel injection allows more of the waste heat from the engine to be directed to the aircraft's cabin during cold weather operations.



Another advantage is that the new higher displacement lower compression ratio engine develops almost 5% more horsepower than the CC340, while also being able to use a wider range of fuels. The company expects that the new engine will be better able to tolerate Autogas and the next generation of aviation fuels than similar higher compression ratio engines.

In addition to the typical fixed pitch wood/composite propellers previously offered with the CC340, the new engine can optionally be fitted with newer ground adjustable propellers, such that pilots can quickly optimise the aircraft for climb or cruise missions without having to change to a completely different propeller. When equipped with the same propeller, the installed weight of the new CC363i F/P engine is only 7 lbs. heavier than the CC340.

Developed as part of a long-standing collaboration between CubCrafters and Lycoming, the new CC363i F/P engine is only available from CubCrafters and offered exclusively on the E/A-B Carbon Cub series of aircraft including the EX-2, EX-3, FX-2, and FX-3. The original Light Sport (LSA) Carbon Cub remains powered by the ASTM certified CC340s.



"It is exciting to be able to introduce this new engine to our customers," says CubCrafters Vice President of Sales and Marketing, Brad Damm, who flew the first CC363i F/P equipped Carbon Cub from the company's base in Washington State to EAA's AirVenture trade show in Wisconsin several weeks ago. "This is an engine our customers have been specifically asking for, especially our kit aircraft customers. It's simple to operate and has better overall performance than any of the other fixed pitch engines we offer. It's smoother, more fuel efficient, and it cools better. Customers who choose this new engine are going to be pleased for sure."

CubCrafters notes that the new CC363i F/P engine is still in the final phases of flight testing at its headquarters in Yakima. Following the completion of the flight test program, new engines should begin shipping to customers as soon as early October. Existing kit aircraft customers with a CC340 currently on order will be prioritised to upgrade to the new engine if they wish.

SKYFLY UNVEILS AXE, KIT-BUILT PERSONAL EVTOL



UK-based eVTOL developer Skyfly recently unveiled Axe, a kit-built personal eVTOL. Axe is currently undergoing certification with the UK's Light Aircraft Association, which would allow it to be flown in most European countries. Skyfly expects to begin production in 2024 and estimate that the eVTOL will sell at a base price of £150,000 (US$180,000).

The twin seat Skyfly Axe has canard wings and four propellers - two attached at each end of each of the two wings; the propellers do not tilt. It is capable of taking off and landing vertically like a helicopter, or conventionally like a fixed-wing aircraft when a runway is available.

Axe has eight electric motors and would be capable of flying 100 miles (160 km) on batteries, or up to 200 miles (322 km) with a proposed lightweight rotary generator.

Michael Thompson, founder of Skyfly said: "Axe's design features are unique in that it has two sets of short wings and the engines are mounted in a 45-degree angle and do not rotate. The wings allow for lift, giving it range and enabling conventional fixed-wing take-offs and the ability to glide at a 10 to one ratio with mechanical linkage if there were to be an engine failure and the redundancy of the eight engines were to be compromised. There is also a third layer of security with a ballistic parachute."



RELIABLE ROBOTICS ACHIEVES MAJOR CERTIFICATION MILESTONE WITH G-1 ISSUE PAPER ACCEPTANCE



Reliable Robotics, a leader in autonomous aircraft systems, today announced that the certification basis of its advanced navigation and auto-flight system has been accepted by the Federal Aviation Administration (FAA). The final G-1 issue paper defines the certification basis for the company's Supplemental Type Certification (STC) on the Cessna 208 Caravan, a popular cargo aircraft.

This STC will enhance safety by enabling continuous autopilot engagement through all phases of aircraft operation, including taxi, take-off, cruise, landing, braking and rollout, with a single pilot on board for abnormal procedures.

"This certification basis is the culmination of years of work with the FAA and represents a key step towards bringing advanced navigation and auto-flight systems to normal category aircraft," said Mark Mondt, Director of Certification at Reliable Robotics.

"We are very appreciative of the FAA's noteworthy attention to detail and ongoing support," said Mark Mondt, Director of Certification at Reliable Robotics. "This certification basis is the culmination of years of work with the FAA and represents a key step towards bringing advanced navigation and auto-flight systems to normal category aircraft. We look forward to continuing our work together as we move into the next phase of the certification process."

The FAA uses issue papers to provide a structured means of describing and tracking the resolution of significant technical and regulatory issues that occur during a certification project. The signed G-1 issue paper represents formal agreement between Reliable Robotics and the FAA on the applicable airworthiness and environmental requirements for the company's advanced automation system.

Today, Controlled Flight into Terrain and Loss of Control are the #1 and #2 causes of fatal accidents in small aircraft. Advanced automation systems will reduce the occurrence of these accidents and bring an unprecedented level of safety to commercial aviation through precision navigation, sophisticated flight planning and robust flight controls.



NORTHROP GRUMMAN'S MQ-8C FIRE SCOUT COMPLETES FIRST EXPEDITIONARY ADVANCED BASE OPERATIONS EXERCISE



Northrop Grumman Corporation's (NYSE: NOC) MQ-8C Fire Scout, the U.S. Navy's autonomous, runway-independent helicopter system, successfully completed operations under the Expeditionary Advance Base Operations (EABO) concept, providing persistent intelligence, surveillance, reconnaissance and targeting (ISR&T) capabilities.

"Fire Scout is the Navy's only unmanned helicopter with the ability to deploy from a ship or land with ISR&T at the extended range required for future warfighting," said Capt. Dennis Monagle, U.S. Navy. "The system is vital in expeditionary use for situational awareness and critical decision-making."

MQ-8C Fire Scout was launched from the Vertical Take-Off and Landing Tactical Unmanned Air Vehicle Maintenance Detachment at Naval Base Ventura County in Point Mugu, California, simulating a ship-based departure. The Navy conducted a control system hand-off of the MQ-8C Fire Scout from Point Mugu to San Clemente Island, California, demonstrating the ship-to-shore transition capability of the platform in a maritime expeditionary environment.

With the Navy's Portable Mission Control Station (MCS-P), the system was recovered and redeployed rapidly for operational flexibility. The portable MCS-P ground control station helps MQ-8C Fire Scout basing in austere locations on land, helipad operations in an advanced forward location, and logistics support from ship flight decks. With identical ship-based hardware, screen configuration and software, operations remain consistent across all ship classes.

"We are supporting MQ-8C deployments on littoral combat ships while assisting the Navy with Fire Scout mission expansion efforts to include operations from other surface ships and shore-based sites," said Lance Eischeid, Director, Fire Scout program, Northrop Grumman. "This EABO demonstration further proves the flexible utility of Fire Scout for expeditionary use from land and across multiple ship classes."

Fire Scout continues Northrop Grumman's 70-year heritage of designing, building, delivering and sustaining the world's most capable unmanned aircraft system.

On 13 April 2022, a Cessna 172M aircraft with registration ZS-SCE, operated by Eagle Air Flying School, was scheduled for night flight training when the incident occurred at Wonderboom Aerodrome, Gauteng province. On-board the aircraft was the instructor and the student pilot.
The flight was intended to be conducted under the provisions of Part 141 of the Civil Aviation Regulations (CAR) 2011 as amended.
The instructor and the student pilot pulled out the aircraft from the operator's hangar onto the apron to conduct pre-flight inspections and start-up procedures. The aircraft was cranked several times during start-up and, later, a bystander who was a distant away from the aircraft observed smoke emanating from the bottom of the engine compartment, followed by flames after engine start.
Thereafter, the bystander ran towards the aircraft, gesturing to the instructor and the student pilot to get their attention to alert them of the smoke and the fire. The fire extinguisher was used to extinguish the fire. The aircraft sustained fire damage to the engine compartment.
The instructor and the student pilot switched off the engine and disembarked from the aircraft. Both were unharmed.
According to https://www.boldmethod.com/learn-to-fly/aircraft, during a cold engine-start, you have to prime the engine. When you prime an engine, you are putting fuel into the cylinders (or the intake manifold) so that the engine can fire. Pilots tend to over-prime the engine by priming to much or to many times (we're guilty of it too). In contrast, there are very few people who prime to little.
The nose engine cowlings, spinner paint and landing light were damaged, as well as the gaskets and plunger were damaged due to heat from the fire and the air-filter and the front baffle rubbers on the carb heat box were damaged.
ēThe carburettor was removed and inspected by the aircraft maintenance organisation (AMO), and it was found undamaged.Probable cause
The engine was over-primed during start-up, resulting in excess fuel catching fire and damaging the engine compartment.



South Africa, Wonderboom Airport: A Piper PA-28-140 Cherokee Cruiser operated by Eagle Air Flight School with two on board aircraft crashed shortly after take-off, it came to rest on its right side. Both occupants received unspecified injuries and were taken to a hospital.

South Africa, Cape Town International Airport: The nose gear of an Airplane Factory Sling 2 collapsed. No further info at the time of publication was available.

South Africa, Bluff, KwaZulu-Natal: A Piper PA-28-140 Cherokee apparently made a forced landing on a beach.

South Africa, Rand Airport, Germiston: A South African Police Service Pilatus Porter, PC-6 with six on board crashed on take-off after one of the wings allegedly broke off. The five passengers did not survive. The pilot suffered serious injuries.



Namibia, Caprivi Strip: A Cessna 210 with five on board on a scenic crashed soon after take-off. There were no survivors.

Nigeria, near Owerri: An Air Peace Boeing 737 on a scheduled passenger flight from Lagos-Murtala Muhammed International Airport to Owerri-Sam Mbakwe International suffered a bird strike on the left main landing gear. The bird got stuck, which 'affected the operating parameters of the landing gear', according to Air Peace. The aircraft returned to Lagos, where it landed without incident.

USA, near Slocomb, AL: A Cessna 140 during the take-off attempt from a private airstrip lost power and impacted trees, and caught fire. The sole pilot onboard received serious injuries.





5 SEPTEMBER 1908



Goupy No.1, is the world's first triplane. The French Goupy, was built by Ambroise Goupy, it had three sets of wings; each stacked above the others and was powered by 50-hp Renault engine.

Unlike previous aircraft built by Voisin, which had been pusher biplanes with a front elevator, the Goupy No.1 was a tractor triplane, with the ends of the wings connected by Voisin's characteristic "side curtains". The tailplane was a Hargrave cell in line with contemporary Voisin practice, with the addition of a pair of small moving elevators mounted on the leading edge of the outer surfaces and a central rudder. The undercarriage consisted of a single wheel mounted below the wing and a tailwheel.

As originally constructed, the middle wing was mounted in a mid-wing position on the fuselage, with the top and bottom wings clear of the fuselage, and power was provided by an Antoinette engine. The design was later revised so that the bottom wing was mounted at the base of the fuselage, the middle wing to the top of the fuselage, and top wings clear of it. At the same time, the engine was changed to an Anzani of similar power and the wings extended outboard of the side curtains, and the single central mainwheel replaced by a pair of wheels.
