Investigation Summary
The flight departed at 02:14 local time in driving rain, carrying 14 passengers and a large cargo of newspapers. Despite the heavy rain, visibility was reported to be approximately 16 kilometres (10 miles). Witnesses observed the aircraft climb at an abnormally steep angle immediately after leaving the runway. At an altitude of roughly 500 feet, the aircraft lost longitudinal stability, stalled, and plunged vertically into the South Guildford housing camp, a former Army site. The wreckage was confined to a small 60-foot by 60-foot area, narrowly missing residential huts. An intense fire, fueled by the cargo of newspapers and fuel, burned for 90 minutes. Investigators found that the center of gravity was likely 3.3% beyond the rear limit due to the overloading of the rear baggage compartment. Although flight tests suggested a DC-3 could remain controllable even further aft of the limit, the combination of the aft CG, heavy rain, and potential instrument maintenance issues created a situation from which the crew could not recover.
Final Conclusions
The official inquiry, tabled in March 1950, concluded that the aircraft stalled for reasons that could not be fully determined from the evidence. However, the report was highly critical of the operator's loading procedures and instrument maintenance. It found that the individual responsible for loading the rear compartment had been untruthful and lacked adequate knowledge of aircraft weight and balance. The inquiry also criticized the Department of Civil Aviation for lax oversight and questioned the qualifications of the Captain, suggesting he should not have been promoted to that rank. Despite recommendations to suspend the airline's license, the Minister for Civil Aviation declined to do so to avoid isolating remote communities.

Airframe & Maintenance
Crew Experience
Captain
Identified as Captain Norman; his qualifications were criticized by the inquiry.
Systems & Failure Modes
Weight and Balance
The aircraft was improperly loaded in the rear baggage compartment, shifting the center of gravity beyond the safe aft limit and reducing longitudinal stability.
Flight Instruments
The inquiry criticized the operator for poor maintenance of cockpit instruments, though their specific role in the crash could not be confirmed due to fire damage.
Interesting Facts
- 01The aircraft was carrying a heavy load of daily newspapers to northern towns, which contributed to the intensity of the post-crash fire.
- 02The center of gravity was calculated to be 3.3% of the Mean Aerodynamic Chord behind the allowable rear limit.
- 03An elevator control chock was found on the tarmac after the crash, but flight tests proved its absence or incorrect placement did not cause the loss of control.
- 04The crash site was a former Army camp used for civilian housing; the aircraft narrowly missed several occupied huts.
- 05All 18 victims were burned beyond recognition, and many were found still strapped into their seats.
Safety Actions & Advisories
Pilot Promotion Oversight
The inquiry recommended that the promotion of pilots to Captain should be at the discretion of the Department of Civil Aviation, taking into account all test records and reports.
Increased Regulatory Vigilance
The Minister for Civil Aviation pledged that the Department would be extra vigilant toward the operator's maintenance and record-keeping standards following the inquiry's criticisms.
