Airworthiness Directives; Bombardier Model DHC-8-100, -200, and - 300 Series Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Bombardier Model DHC-8-100, -200, and -300 series airplanes. This action requires the removal and testing of sections of bonded skin from the upper and lower skin panels of the horizontal stabilizer, repair of those areas, and follow-on corrective actions, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent reduced strength capability and consequent failure of the horizontal stabilizer, which could result in loss of controllability of the airplane.
