Airworthiness Directives; Robinson Helicopter Company Model R-22 Series Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) for the specified Robinson Helicopter Company (Robinson) Model R-22 series helicopters that have been modified in accordance with Supplemental Type Certificate (STC) No. SR09189RC. This action requires inspecting the left-hand door and right-hand door for a crack in the door assembly integral frame, and replacing the door assembly if a crack is found. This AD also requires inspecting each door assembly to determine if the weather seal set is airworthy and installed properly, inspecting each door hinge for the proper installation of a cotter pin, and thereafter, at intervals not to exceed 100 hours time-in-service (TIS), inspecting each door assembly integral frame for a crack. This amendment is prompted by one accident and one incident involving Robinson Model R-22 series helicopters. The actions specified in this AD are intended to prevent separation of a door window or door assembly from the helicopter, which could damage the tail rotor during flight and result in loss of control of the helicopter.

Repetitive inspection. Re-inspect every 100 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applies only to helicopters modified with a door assembly manufactured by Tech-Tool Plastics, Inc., in accordance with STC No. SR09189RC. Certificated in any category.

Whether AD 2005-16-05 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 2005-16-05 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
