Airworthiness Directives; Honeywell International Inc. TPE331-10 and TPE331-11 Series Turboprop Engines

Document Number: 2011-20170

Type: Proposed Rule

Date: 2011-08-09

Agency: Federal Aviation Administration, Department of Transportation

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require inspecting certain serial number (S/N) first stage turbine disks, part number (P/ N) 3101520-1 and P/N 3107079-1. This proposed AD was prompted by a report of an uncontained failure of a first stage turbine disk that had a metallurgical defect. We are proposing this AD to prevent uncontained failure of the first stage turbine disk and damage to the airplane.
