[3] In June 1994, the MoD test pilots at Boscombe Down had refused to fly the Chinook HC.2 until the engines, engine control systems and FADEC software had undergone revision. On 25 May 1994, a serious incident occurred which had indicated the imminent failure of the No.2 engine. [40] Information on speed and height were derived from the position of cockpit dials in the wreckage, and the wreckage's condition. Had they made it to Fort George, they would have needed special permission from a senior officer to fly back to Aldergrove.

The 2011 Review concluded that criticism that the original board had not paid enough attention to maintenance and technical issues was unjustified. [37], The onboard Tactical Air Navigation System, which only retained the last measured altitude, gave an altitude reading of 468 feet. The wreckage of the Chinook (Chris Bacon/PA) The Chinook pilots, flight lieutenants Jonathan Tapper and Richard Cook, were accused of gross negligence over the crash. It was expected that in a FADEC engine runaway, engine power would become asynchronous and mismatched. Rescuers rush to save beached pilot whales. The 2011 Parliamentary report found the reviewing officers to have failed to correctly adhere to the standard of proof of "absolutely no doubt" in deciding the question of negligence. [11][12] It was announced on 8 December 2008 by Secretary of State for Defence John Hutton that "no new evidence" had been presented and the findings of gross negligence against the flight crew would stand. In 2011, MoD minister Lord Astor said the exact cause of the crash will never be known and pursuing the matter further would only serve to increase the distress of the family and friends of those who died. On arrival at RAF Odiham, its No.1 engine had to be replaced. 'active' : ''"> A Parliamentary inquiry conducted in 2001 found the previous verdict of gross negligence on the part of the crew to be ‘unjustified’.

This ruling was subsequently overturned by two senior reviewing officers who said the pilots were guilty of gross negligence for flying too fast and too low in thick fog. To accept the verdict against the pilots is to accept that it is reasonable to blame the operators if the cause of a disaster is not known. Please A Parliamentary inquiry conducted in 2001 found that the previous verdict of gross negligence on the part of the crew to be 'unjustified'. MoD subsequently claimed it did not have its own copy, calling into question how it could advise Spellar one way or the other. “unverifiable and … therefore unsuitable for its purpose”. Had they made it to Fort George, they would have needed special permission from a senior officer to fly back to Aldergrove.

The deaths of 25 senior police, army and MI5 officers - some of the most experienced intelligence experts in the country - were described by the Chief Constable of Northern Ireland as a "catastrophic loss in the fight against terrorism".

Aviation safety author Andrew Brookes wrote that the true cause will never be known, but that pilot error induced by fatigue is likely to have played a part; the crew had been on flight duty for 9 hours and 15 minutes, including 6 hours flying time, before they took off on the crash flight. The MoD has said that records closed in 1995 and 1996 will be reviewed for release or disposal this year and a decision will be made in due course. In the area around the Mull of Kintyre, the safe altitude would be 2,400 feet (730 m) above sea level, 1,000 feet (300 m) above the highest point of the terrain. 'active' : ''"> Are you sure you want to submit this vote? [20][22], On 31 May 1994, two days before the accident, two Chinook HC.1s were withdrawn from RAF Aldergrove and replaced by a single HC.2, ZD576. In December 2012, the Minister for the Armed Forces, Andrew Robathan, confirmed such a false declaration did not constitute "wrongdoing", despite it leading directly to deaths of servicemen. 1953: Queen Elizabeth takes coronation oath, 1979: Millions cheer as the Pope comes home, 1994: MI5 officers killed in helicopter crash, 1985: Uefa bans English clubs from Europe, 1976: Piggott celebrates 7th Derby victory. continue to respect all commenters and create constructive debates. That is why the loss of Chinook ZD576 is so much more than a helicopter crash. The campaign for a new inquiry was supported by the families of the pilots, and senior politicians, including former Prime Minister John Major and former Defence Secretary Malcolm Rifkind. [22] In October 2001, Computer Weekly reported that three fellows of the Royal Aeronautical Society had said that issues with either control or FADEC systems could have led to the crash. There were two other crew. [40], The main submission to Lord Philip (see above) revealed that the FADEC Safety Critical software did not have a Certificate of Design, and was therefore not cleared to be fitted to Chinook HC2. [1], Around 18:00, Chinook ZD576 flew into a hillside in dense fog. That is why the loss of Chinook ZD576 is so much more than a helicopter crash. According to the House of Commons report: "After examining only 18 per cent of the code they found 486 anomalies and stopped the review... intermittent engine failure captions were being regularly experienced by aircrew of Chinook Mk 2s and there were instances of uncommanded run up and run down of the engines and undemanded flight control movements". What does developing a Covid-19 vaccine look like? [26] Nine out of ten witnesses interviewed in the inquiry reported visibility at ground level in the fog as being as low as ten to one hundred metres at the time of the crash, however in-flight visibility may have been more or less than this. In his book, Steuart Campbell suggested that two errors by the pilots; failure to climb to a safe altitude upon entering cloud, and a navigational error made in the poor visibility (mistaking a fog signal station for a lighthouse), together caused the crash. Among these were accusations that wake turbulence from a top-secret hypersonic US aircraft had been responsible for the crash, while another postulated that it was a deliberate assassination of the intelligence operatives on board in connection with the then on-going Northern Ireland peace process. If witness accounts of visibility are correct, the pilots should have transferred to Instrument Flight Rules, which would require the pilots to slow the aircraft and climb to a safe altitude at the best climbing speed. On 10 May 1994, a post-flight fault inspection revealed a dislocated mounting bracket causing the collective lever to have restricted and restrictive movement. However, it announced in a later statement that, after further reflection, it had been decided to release their names. When the crew released the computer from its fix on the Mull, the pilots knew how close to the Mull they were and, given the deteriorating weather and the strict visibility requirements under visual flight rules they should by that time already have chosen an alternative course. Contractors, including Textron, had agreed that FADEC had been the cause of the 1989 incident and that the system needed to be redesigned. RAF Visual Flight Rules (VFR) require the crew to have a minimum visibility of 5.5 kilometres above 140 knots (260 km/h), or minimum visibility of one kilometre travelling below 140 knots; if VFR conditions are lost an emergency climb must be immediately flown. An immediate suspicion that the helicopter could have been shot down by the Provisional IRA, with their known Strela 2 surface-to-air missile capability, had been quickly ruled out by investigators.
