Airworthiness Directives; Mooney Aircraft Corporation Model M20R Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to certain Mooney Aircraft Corporation (Mooney) Model M20R airplanes. This AD requires either fabricating and installing a placard that specifies using the air conditioning system during cruise operations only or deactivating the air conditioning system so it cannot be used. This AD is the result of reports of the existence of dangerous levels of carbon monoxide during taxi, climb, and descent operations of the above-referenced airplanes. The actions specified by this AD are intended to prevent dangerous levels of carbon monoxide from entering the airplane cabin during takeoff, climb, and descent operations caused by the present flight cabin sealing design of the affected airplanes, which could result in passenger injury.

Which aircraft AD 99-11-07 applies to

MakesMooney

Boilerplate applicability only; the specific Mooney model/serial-number list precedes this excerpt and is not included. Requires either fabricating and installing a placard restricting air conditioning use to cruise only, or deactivating the air conditioning system, per Mooney Service Bulletin M20-270 (issued March 1, 1999), to prevent dangerous levels of carbon monoxide from entering the cabin during takeoff, climb, and descent due to the flight cabin sealing design.

Whether AD 99-11-07 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 99-11-07 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.
