From the Wikipedia article

On Tuesday 16 May 1995, a Royal Air Force Nimrod R1 aircraft suffered an in-flight engine fire which led to the aircraft having to ditch in the Moray Firth. This was the first of two Nimrods to be lost in 1995; it was followed by the crash of a Nimrod MR2 in Canada in September.

Crash details

On 16 May 1995, following the completion of major servicing work, XW666 had departed RAF Kinloss on a routine air test flight with a crew of seven on board. Thirty-five minutes into the flight, after a test of the anti-icing system, the fire warning light of number 4 engine came on. At this, the crew began the fire drill procedures but, while this was taking place, the warning light for the number 3 engine also illuminated. Following this, a member of the crew confirmed that the aircraft was indeed on fire, with panels falling from the starboard wing. At this point, the captain, who had attempted to divert to RAF Lossiemouth, elected to instead try and ditch the aircraft in the Moray Firth, as it was unclear whether the structural integrity would hold, and whether control could be maintained any longer. Despite the lack of flaps, which were not functional due to hydraulic failure associated with the fire, the pilot was able to make a controlled ditching on the waters of the Moray Firth. This caused the fuselage to break into two pieces, which eventually sank.

Investigation and cause

Cause

Following an inquiry by the Air Accident Investigation Branch and the RAF, it was determined that the DC loom on the aircraft's Number 4 engine had somehow sustained damage prior to the flight. An arc occurred when the anti-icing system was turned on, which led to the engine air start sequence initiating. The engine was running idle as part of the testing regime during the flight, so when the starter turbine ran up to high speed, it caused a structural failure that led to the turbine disc puncturing one of the fuel tanks. The fuel leak was subsequently ignited, either by the high engine temperature, or the arc from the faulty loom.
