For those who have not been involved with this long debate and may not know what we are talking about, this is an extract from the evidence given to the HoL enquiry by Squadron Leader Burke:
109. Squadron Leader Burke spoke to having experienced two engine run ups on the ground at the Boeing factory in Philadelphia while flying with an American Army test pilot (Q 655) and similar run ups when testing the overspeed limiter on the ground at Odiham (Q 680). He also spoke to problems with the multi-point connectors which went from the engines into the DECU. These were of bad design and liable to be displaced by vibration which then produced a power interruption. Although there was a back-up system this did not always work and on two or three occasions pilots had lost control of the engine condition lever. As a result squadrons introduced a procedure whereby crewmen every quarter of an hour checked that the connections had not been displaced in flight (QQ 677-9).
Sqdn Ldr Burke, who carried out much of the test flying on the Chinook, was not asked to give evidence at the original BoI
