Airworthiness Directives; EXTRA Flugzeugbau GmbH Model EA-300/S Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to certain EXTRA Flugzeugbau GmbH Model EA-300/S airplanes. This AD requires modifying the canopy latches or replacing the canopy latches with parts of improved design. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to prevent failure of the canopy while the airplane is in flight because of cracked canopy latches, which could result in loss of the canopy and possible loss of control of the airplane.

Which aircraft AD 98-04-01 applies to

MakesExtra Flugzeugbau

Part-conditional — PC-23303.8P1, PC-23303.8P2.

Prevents canopy failure from cracked canopy latches; requires modifying/replacing all canopy latches with improved-design parts (P/N PC-23303.8P1 for front/rear-right latches, P/N PC-23303.8P2 for rear-left) per EXTRA Service Bulletin No. 300-3-94, dated August 3, 1994 (also German AD 94-258). Text does not state a specific model designation beyond the manufacturer EXTRA Flugzeugbau GmbH.

Whether AD 98-04-01 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 98-04-01 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.
