Airworthiness Directives; The New Piper Aircraft, Inc. Model PA- 46-350P Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to certain The New Piper Aircraft, Inc. (Piper) Model PA-46- 350P airplanes. This AD requires installing reinforcement plates to the wing forward and aft attach fittings. This AD is the result of a report that sheet steel material that is below design strength standards may have been utilized on the wing attach fittings on the Model PA-46-350P airplanes manufactured since January 1995. The actions specified by this AD are intended to prevent structural failure of the wing attach fittings caused by the utilization of substandard material, which could result in the wing separating from the airplane with consequent loss of control.

Which aircraft AD 99-16-06 applies to

MakesThe New Piper Aircraft, Inc.
Part-conditional — 766-656.

Extracted text begins at the standard 'preceding applicability provision' boilerplate; the AD's actual airplane model list precedes this excerpt and was not captured by extraction. Prevents potential failure of the wing attach fittings caused by use of substandard material, which could result in the wing separating from the airplane with consequent loss of control. Requires, within 100 hours TIS, installing reinforcement plates on the wing forward and aft attach fittings via the Wing to Fuselage Reinforcement Installation Kit, Piper part number 766-656 (dated November 6, 1998), per Piper Service Bulletin No. 1027, dated November 19, 1998.

Whether AD 99-16-06 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 99-16-06 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.
