                This Airworthiness Directive becomes effective on 1 September 2005.
Background:     Transport Canada has received advice from BHTC that due to manufacturing discrepancies, the performance of torque indicators manufactured by Ahlers Aerospace in cold weather may be affected resulting in lower than actual readings.

                This Directive requires the inspection of all installed torque indicators to determine their part number and, if necessary, their replacement.
