Airworthiness Directive · Amendment 39-10462 · Eurocopter France Model SA 330F, G, and J, and AS 332C, L, L1, and L2 Helicopters
Eurocopter France Model SA 330F, G, and J, and AS 332C, L, L1, and L2 Helicopters
Model SA 330F, G, and J helicopters with tail rotor head pitch change spider arm (spider arm), part number (P/N) 330A330104.20 or .21, or 332A330039.20 or .21, installed and Model AS 332C, L, L1, and L2 helicopters with spider arm, P/N 332A330039.20 or .21 installed, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France Model SA 330F, G, and J, and AS 332C, L, L1, and L2 helicopters. This action requires daily inspections of the root of each tail rotor head pitch change spider arm (spider arm) for cracks, and an inspection of the tail rotor head pitch change spider (spider) for cracks and fretting corrosion. A terminating action for the requirements of this AD is the installation of an airworthy modified spider, an airworthy replacement spider, or an airworthy repaired spider. This amendment is prompted by one in-service report of fatigue cracking on a Model AS 332 helicopter. This condition, if not corrected, could result in failure of the spider arm, loss of control of the tail rotor blade, and subsequent loss of control of the helicopter.
