Corrosion

August 8, 2012 - 1:20pm

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 proposed an Airworthiness Directive for the Eurocopter SA365N, SA365N1, AS365N2, AS365N3, EC155B, EC155B1, SA365C, SA365C1, SA365C2 and SA366G1. It is prompted by reports of corrosion on the main gearbox (MGB) casing lower area between the two servo-control anchor-fitting attachment ribs. The proposed actions are to detect corrosion on the MGB casing, which could lead to a crack, failure of the MGB and subsequent loss of control. The FAA is accepting comments until August 17.
