FAA20210449; Project Identifier 2018SW001AD.
a Effective Date This airworthiness directive AD is effective October 13, 2021.
b Affected ADs None.
c Applicability This AD applies to Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, and AS350D
helicopters; and Model AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP
helicopters, certificated in any category, with litter kits installed having any part number specified in paragraphs c1 through 3 of this AD:

3 P/N 350200144 right-hand litter kit.
d Subject Joint Aircraft Service Component JASC
Code: 6700, Rotorcraft Flight Control.
e Unsafe Condition This AD was prompted by reports that the lanyards bead chain tethers, which hold the quick release pins to the forward bracket assembly of certain litter kits, can loop around the directional control pedal stubs, limiting the movement of the pedals, which affect the control of the flight. The FAA is issuing this AD to address interference between the litter kit lanyards and the flight controls. The unsafe condition, if not addressed, could result in limited flight control movement and difficulty controlling the helicopter.
