From the Kohn report:
8.4
To illustrate the number of engine problems, these accounted for a fourth of all Chinook mishaps in the (United States Services) Financial Year 1998. The areas that most needed attention are the torque-metering system and power controls. The Chinook community is anxiously waiting the fielding of the upgrade T-55GA-714A engine which will bring improvements to all areas of the
power plant, including the full authority digital electronic control (FADEC) system. The T-55GA-714A engine has proved itself on special-operations aircraft where it drastically reduced the number of engine related accidents.

Q1. Have the the torque-metering system and power controls been modified since the Mull of Kintyre crash in June 1994?
Q2. Do RAF Chinooks have the T-55GA-714A engine (or an equivalent model) and, if so, was this retro-fitted at some stage since June 1994?
