leaks or oil filter contamination) prior to the effective date of this directive, within five (5) hours time in service or 30 days after the effective date of this directive, whichever occurs first.

                For all other engines, within the next 50 hours time in service, or 6 months after the effective date of this directive, whichever occurs first.
                3. For Twin Engine-Powered Aircraft:

                For engines which exhibited in-service difficulties (such as oil leaks or oil filter contamination) prior to the effective date of this directive, within ten (10) hours time in service or 60 days after the effective date of this directive, whichever occurs first.

                For all other engines, within the next 100 hours time in service, or 12 months after the effective date of this directive, whichever occurs first.
             This Airworthiness Directive becomes effective on 16 March 2006.
Background:  Transport Canada has received several reports of disassembly of engines (to correct in-service defects) that were overhauled or repaired by B.C. Aero Engines Ltd.  With numerous non-conformities on the engines.  Further investigation carried out by Transport Canada has determined certain Teledyne Continental Motors reciprocating engines that have been overhauled, repaired or disassembled by B.C. Aero Engines Ltd. are not in conformance with the manufacturer's overhaul data and have serious quality issues that may result in an unsafe situation.  Transport Canada cancelled B.C. Aero Engines' AMO (84-02) on 18 July 2004.

             The above situation, if not corrected, may result in an in-flight engine failure.
