Background
The Air Accidents Investigation Branch (AAIB) published Aircraft Accident Report 1/2009 covering a series of serious incidents at Bristol International Airport. The incidents occurred on Runway 27 and involved multiple aircraft on 29 December 2006 and 3 January 2007.
Incidents
On 29 December 2006, three aircraft experienced serious incidents: a Boeing 737-81Q registered G-XLAC, an Avions de Transport Regional ATR-72-202 registered G-BWDA, and an Embraer EMB-145EU registered G-EMBO. A fourth incident involved the same Boeing 737-81Q (G-XLAC) on 3 January 2007. All incidents occurred on Runway 27 at Bristol International Airport.
The report includes sections on the history of each flight, injuries to persons (none specified as fatal or serious in the source), damage to aircraft, and other damage. It also details personnel information, aircraft information for each type (including control systems, brake systems, and performance), and meteorological information for both dates.
Investigation
The investigation examined runway conditions, including reported braking action and runway surface characteristics. The report discusses runway resurfacing work that had been carried out at Bristol International Airport and subsequent rectification work following the incidents. It also covers flight recorder data analysis, such as deceleration versus runway position and braking coefficient for G-XLAC, as well as lateral effects for G-BWDA and G-EMBO. Aircraft examinations were conducted on all three aircraft.
The report includes additional information on friction measuring equipment, previous runway resurfacing works at other airports (Luton and Belfast City), risk assessment by the airport, hydroplaning considerations, and a reference to a similar investigation by the National Transportation Safety Board (NTSB) in the USA. Organizational and management information from ICAO and the CAA is also presented.
The AAIB report does not state a probable cause in the provided source excerpt.
