Airworthiness Directives; EXTRA Flugzeugbau GmbH Model EA-300 Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to certain EXTRA Flugzeugbau GmbH (EXTRA) Model EA-300 airplanes. This AD requires removing the elevator mass balance assemblies and replacing them with reinforced elevator mass balance assemblies 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 damage and possible jamming of the airplane's control system, which, if not corrected, could cause loss of control of the airplane.

Which aircraft AD 98-06-03 applies to

MakesExtra Flugzeugbau, Gmbh
ModelsEA-300
Part-conditional — PC-33202.1B.

Within next 50 hours TIS after effective date, replace the elevator mass balance assemblies with new reinforced assemblies, P/N PC-33202.1B (or FAA-approved equivalent), per EXTRA EA-300 Elevator Mass Balance SB No. 300-1-92 Issue A (March 27, 1992). Prevents possible jamming of the airplane's control system, which could cause loss of control.

Whether AD 98-06-03 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 98-06-03 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.
