Airworthiness Directives; SOCATA-Groupe AEROSPATIALE Model TB 21 Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to certain SOCATA--Groupe AEROSPATIALE (Socata) Model TB 21 airplanes. This AD requires you to modify the exhaust system. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified by this AD are intended to prevent high levels of carbon monoxide from entering the cockpit during certain flight configurations, which could result in the pilot becoming incapacitated or impairing his/her judgement. Such a condition could lead to the pilot not being able to make critical flight safety decisions and result in loss of control of the airplane.

Specific serial/registration applicability (paragraph (a)) not present in retrieved text. Actions per Socata TB Aircraft Mandatory Service Bulletin SB 10-126-78, dated November 2001; special flight permits restricted to no-passenger ferry flights.

Whether AD 2002-20-04 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 2002-20-04 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.
