Airworthiness Directive · Amendment 39-11204 · Robinson Helicopter Company (Robinson) Model R44 Helicopters
Robinson Helicopter Company (Robinson) Model R44 Helicopters
Model R44 helicopters, Serial Numbers 0002 through 0529 except 0440, 0485, 0512, 0515, 0519, 0526, 0527, and 0528, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to Robinson Model R44 helicopters, that requires installing a shutoff clamp on the auxiliary fuel tank sump drain tube (drain tube) and a placard decal to alert operators as to the proper use of the auxiliary fuel tank drain. This amendment is prompted by a report of fuel leaking from a drain tube opening in the area of the horizontal and vertical firewalls. The actions specified by this AD are intended to prevent fuel leaks from the drain tube that could cause a fire and subsequent loss of control of the helicopter.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
