Peter and Norma Quilliam, a retired couple from the United Kingdom, died on 30 August 2004 when their Cessna 421C aircraft crashed shortly after takeoff from El Questro Wilderness Park airstrip in remote Western Australia. The aircraft became airborne within less than half the runway distance, then banked left at very low altitude (approximately 50 feet), with the left wing dropping rapidly before impacting trees and the ground. Both occupants died from incineration in the resulting fire. Post-mortem examination of the pilot revealed no medical conditions that could have contributed to the crash. Despite comprehensive investigations by police and the Australian Transport Safety Bureau, the precise cause could not be determined. The ATSB concluded there was no evidence of aircraft malfunction, but suggested the pilot may have been distracted by an unidentified event during takeoff, or alternatively may have attempted early liftoff to avoid runway debris damage. The coroner found the death was accidental and made recommendations regarding regulatory oversight of commercial-use airstrips.

Coroner's recommendations
CASA should review the current regulatory situation in relation to Aircraft Landing Areas which are regularly used in a commercial context
CASA should consider taking steps to alter regulatory provisions so that Aircraft Landing Areas used regularly in commercial context are subject to CASA approval and inspections
Such inspections should be conducted to ensure that runways are maintained in a safe condition
Inspections should ensure that Civil Aviation Advisory Publication guidelines in respect of lateral clearance are complied with in other than exceptional circumstances
