Robinson Helicopter Company Helicopters
This AD applies to Robinson Helicopter Company R22, R22 ALPHA, R22 BETA, R22 MARINER.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 95-11-09 which was sent previously to all known U.S. owners and operators of Robinson Helicopter Company (Robinson) Model R22 helicopters by individual letters. This AD requires installation of a placard in the helicopter, and insertion of a prohibition against low-gravity (G) cyclic pushover maneuvers into the LIMITATIONS section of the Rotorcraft Flight Manual. This amendment is prompted by a recent Federal Aviation Administration (FAA) analysis of the manufacturer's data that indicates a low-G cyclic pushover maneuver may result in mast-bumping on the Robinson Model R22 helicopters. The actions specified by this AD are intended to prevent in-flight main rotor separation or contact between the main rotor blades and the airframe of the helicopter, 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.
