5 January 1969 - Ariana Afghan Airlines 701

Ariana Afghan Airlines, Flight 701, a B727-113C with registration YA-FAR, was carrying out a runway 27 approach into London Gatwick with the autopilot coupled to the ILS because of bad weather (freezing fog and an RVR of 100m). The 'stabilizer out of trim' warning light illuminated shortly after glide slope capture. The captain responded by disconnecting the autopilot. After passing the Outer Marker flaps were changed from 15deg to 30deg and the rate of descent increased. The aircraft descended below the glide slope until the pilot realised that the aircraft was too low (200ft agl). A missed approach was executed, but the descent was not arrested in time to avoid a collision with trees and a house.

01.20 LAW: gives permission to descend to 8000ft
01.23 LAW: 701, London. I just checked Gatwick. The runway remains ... the range remains at ... er ... 100 metres and there's no sign of improvement at the moment.
  RDO-CPT: We'll try Gatwick ... er ... if we cannot make it at gatwick will it be OK if we go to Heathrow?
  LAW: acknowledges the question and clears the flight to 5000ft with a direct course to Mayfield beacon.

  RDO-CPT: acknowledges runway number and barometric pressure.
  APP: Er ... 701, do you wish to make an approach?
  RDO-CPT: That's affirmative.
  APP: clears 701 down to 2000ft
  CPT: It's ground fog, not air fog
