| 2012-30925 | Airworthiness Directives; Bombardier, Inc. Airplanes | Proposed Rule | We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, and -106 airplanes, and Model DHC-8-200, -300, and -400 series airplanes. This proposed AD was prompted by reports of excessive wear found in the clevis (bolt) hole where the rod assembly attaches to the rudder/brake pedal bellcrank, due to prolonged fretting. This proposed AD would require measuring the bellcrank clevis holes, inspecting for cracking of the bellcrank, and re-working the clevis holes with steel bushings, or replacing the bellcrank. We are proposing this AD to detect and correct a worn or cracked clevis hole, which could cause failure of the bellcrank on one side, with subsequent asymmetric braking and consequent runway excursion. | 2012-12-26 | 2012 | 12 | https://www.federalregister.gov/documents/2012/12/26/2012-30925/airworthiness-directives-bombardier-inc-airplanes | https://www.govinfo.gov/content/pkg/FR-2012-12-26/pdf/2012-30925.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc.
