Accidents & Serious Incidents involving DH8D

• B763/DH8D, Fukuoka Japan, 2010 (RI HF) (On 10 May 2010, the TWR controller at Fukuoka cleared a Bombardier DHC8-400 to land on runway 16 and then a minute later whilst it was still on approach cleared a Boeing 767-300 to line up and take off on the same runway. Only a query from approaching aircraft which had been cleared to land prompted by hearing a take off clearance being given for the same runway alerted ATC to the simultaneous runway use clearances. As it was too late to stop the departing aircraft at the holding point, its clearance was changed to “line up and wait” and the approaching aircraft was instructed to go around.)
• DH8D / B735, Exeter UK, 2009 (RI HF) (On 30 October 2009, a Bombardier DHC8-400 being operated by Flybe on a scheduled passenger flight from Exeter to Edinburgh failed to follow its acknowledged ATC taxi out clearance to the runway holding point 08 and entered and lined up on the active runway at night in normal visibility at the same time as a Boeing 737-500 being operated by Astraeus Airlines on a non revenue positioning flight to Exeter, was landing on the opposite (26) direction of the same runway.)
• DH8D / TOR, en-route, North Sea UK, 2008 (AI LOS) (On 13 October 2008, a DHC-8 Q400 executed ATC instructions, followed by TCAS TA and RA to avoid unknown traffic. Recorded minimum lateral separation was 2.5 NM.)
• DH8D, Bournemouth UK, 2010 (LOC HF AW) (On 30 November 2010, a Bombardier DHC8-400 being operated by Flybe on a scheduled passenger flight from an unrecorded origin to Southampton was unable to select any trailing edge flaps when preparing for the intended landing at destination. The night non precision approach in VMC was discontinued and a diversion was made to Bournemouth where a longer runway with an ILS procedure was available for the necessary flapless landing and during the subsequent touchdown, a tail strike occurred. None of the 73 occupants were injured and damage to the aircraft was minor.)
• DH8D, Chania Greece, 2010 (RE HF) (On 23 February 2010, a Bombardier DHC8-400 being operated by Flybe for Olympic Air on a scheduled passenger flight from Athens to Chania unintentionally made an approach at destination in day VMC towards a landing on a part of the runway which was closed and only corrected the profile shortly before touchdown to achieve an ultimately uneventful landing on the available part of the runway. None of the 55 occupants were injured.)
