Enstorm 280C Shark G-IDUP was damaged in an emergency/forced landing near Lynchmere, 2.5 nautical miles South West of Haslemere, Surrey.
In the early evening of 6 May 1993 Enstrom 280 Shark G-IDUP was being flown from Goodwood Airfield near Chichester to Tongham, near Farnham, Surrey when, at about 1,400 feet over the Haslemere area, the helicopter lurched sharply and the pilot felt vibrations through the rudder pedals. Thus he cut the power and made an immediate auto-rotation landing, touching down in a field of barley a little under 3 miles from Haslemere. The pilot was uninjured and the helicopter suffered no further damage.
Subsequent inspection of the helicopter revealed that it had lost one of the two bolts (together with its nut, split pin, washer and spacers) which attaches the tail rotor pitch link to the blade pitch arm. Because these elements were not recovered, the cause of their dislocation and loss could not be determined. However it appears that this was not an isolated incident for this type of helicopter and it was opined that the design of the bolt, its spacers, nut and split pin was inadequate and that the bolt could be susceptible to metal fatigue.
The bolt is the subject of a CAA Airworthiness Directive, which requires its inspection (and, if necessary, replacement) every 100 flying hours. The bolt on G-IDUP was the subject of a pre-flight inspection on 6 May 1993 when, presumably, nothing untoward was seen.
G-IDUP was built in 1979, and first registered in the USA as N5687D. It was first UK registered as G-BZRF on 12 March 1990. It was then re-registered as G-IDUP on 11 May 1992. After going through three owners, it was restored to its previous registration of G-BRZF on 18 September 2017. On October 5th 2021 the regsitration G-BRZF was cancelled as "Permanently withdrawn from use".
