Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Bombardier Model DHC-8-401 and -402 airplanes. This action requires a records review to determine the repair/ modification status of the airplane, and follow-on and corrective actions as necessary. This action is necessary to prevent cracks in the lower fuselage skin due to fatigue damage in the vicinity of the Number 2 VHF antenna, which could result in rapid decompression of the airplane. This action is intended to address the identified unsafe condition.
