Until Bombardier develops a fix and it is FAA approved, operators of about 255 U.S.-registered Learjet 23s through 25s will be required to disable the thrust reversers. In a proposed AD, the FAA says it has two reports of the reverser accumulators failing, which also caused loss of hydraulic power. The failures were caused by fatigue cracking, according to the agency.
