Summary
The FAA proposes to supersede Airworthiness Directive (AD) 98-03-14, which applies to certain EXTRA Flugzeugbau GmbH (EXTRA) Model EA-300 and EA-300/S airplanes. AD 98-03-14 currently requires you to inspect the upper longeron cutout-bridge for cracks, repairing any cracks found, and modifying this area. This proposed AD would retain the actions of AD 98-03-14 and incorporate new service information. For owner/operators of the affected airplanes that were able to do the modification required in AD 98-03-14, no further action would be required. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this proposed AD to detect and correct cracks in the upper longeron cutout-bridge, which could cause the upper longeron cutout-bridge to fail resulting in structural damage to the fuselage. This condition could lead to loss of control of the airplane.
