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

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to EXTRA Flugzeugbau GmbH Models EA-300 and EA-300/S airplanes. This AD requires inspecting the upper longeron cutout bridge for cracks, repairing any cracks found, and modifying this area. 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 structural damage to the fuselage caused by cracks in the upper longeron cutout bridge, which, if not detected and corrected, could result in loss of control of the airplane.

Which aircraft AD 98-03-14 applies to

MakesExtra Flugzeugbau

Prevents fuselage structural damage from cracks in the upper longeron cutout bridge; inspect at 1,000 hours TIS on the upper longeron (or within 100 hours TIS after effective date, whichever is later), then repair/modify per EXTRA Service Bulletin No. 300-3-93, dated January 12, 1994. Text does not state a specific model designation beyond the manufacturer EXTRA Flugzeugbau GmbH.

Whether AD 98-03-14 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.

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.
