Lyon, France-based fuel-leak repair specialist Sunaero (also known as Aerowing in the U.S.) is offering its services to the helicopter industry, pledging significant time savings over conventional detection and repair methods.

Increasingly complex fuel-tank shapes have raised new challenges, Sunaero vice president Thierry Regond told AIN. Small but serious leaks, whether they originate from vibration wear or manufacturing defects, are difficult to locate and can force missions to be scrubbed, as one European country’s police force recently discovered, Regond said.

Twin Commander Aircraft has developed a pressurization leak kit for rudder-pedal horns. Leaks in the boots that enclose the rudder-pedal horns can result in a noticeable loss of pressure differential, meaning a higher cabin altitude at cruise. Twin Commander’s new rudder-pedal seal kit includes a plug for the rudder-pedal horns/brake valve arms and improved boots that help preserve cabin pressurization.

Twin Commander Aircraft has developed a rudder-pedal seal kit that it says virtually eliminates pressurization leaks in a troublesome area. Leaks in the original boots that enclose the rudder-pedal horns can lead to a noticeable loss of pressure differential, resulting in a higher cabin altitude at cruise. Twin Commander’s new rudder-pedal seal kit includes a plug for the rudder-pedal horns/brake valve arms and improved boots that help preserve cockpit and cabin pressurization.

An FAA Airworthiness Directive targeting certain Gulfstream Astra SPX, 1125 Westwind Astra and Gulfstream 100s was prompted by sponge rubber padding found between wheel well fuel lines and electrical harnesses to provide separation. The padding is not approved and may cause corrosion of the fuel lines. Uncorrected, it could cause corrosion damage and/or chafing resulting in fuel leakage, which could result in a wheel-well fire.

The FAA is proposing to rescind an Airworthiness Directive (AD 200-07-11) issued for all Piaggio Avantis to prevent the brake hydraulic fluid from leaking. It was prompted by reports of brake assembly rods contacting the brake valve tubing, which could compromise the airplane’s ability to stop during ground operations. Since then the FAA has determined it is no longer an unsafe condition and that regularly scheduled annual inspections address the subject. The FAA is taking comments until September 4.

Transport Canada last month notified the FAA of a potentially dangerous fuel system defect in Bombardier’s new CRJ700 regional jet, prompting the U.S. agency to issue an emergency AD for the model. According to Transport Canada, CRJ700s may experience uncommanded fuel transfer between the wing tanks and the center tank, creating a condition in which the center tank can overfill and leak.
