Hello Butch13,
The Aviation Safety Network provides detailed accident descriptions
for major airline accidents.
Here is the detailed information about the airplane crash that
occurred in Ljubljana (Slovenia) in 1966.
Date: 01 SEP 1966
Time: 00.47
Type: Bristol 175 Britannia 102
Operator: Britannia Airways
Registration: G-ANBB
Msn / C/n: 12903
Year built: 1954
Total airframe hrs: 18444 hours
Cycles: 5380 cycles
Crew: 6 fatalities / 7 on board
Passengers: 92 fatalities / 110 on board
Total: 98 fatalities / 117 on board
Location: Ljubljana (Slovenia)
Phase: Final Approach
Nature: Int'l Non Scheduled Passenger
Departure airport: London-Luton Airport (LTN)
Destination airport: Ljubljana-Brnik Airport (LJU)
Flight number: 105
Remarks:
“The Britannia aircraft approached Ljubljana runway 31 at night when
it crashed into trees.”
PROBABLE CAUSE:
"The probable cause of the accident was that the pilot-in-command did
not set his altimeter to the QFE-968 mb in accordance with the
information passed by the controller. However, the whole approach to
the airport was made as if the altimeter had been set to the QFE, and
resulted in the approach being about 1250ft lower than procedural
safety altitudes, so that the aircraft's approach was too low, bacause
although it was a moonlight night he could not distinguish any visual
land marks, which might have warend him of the low altitude, due to
the nature of the trees covered terrain over which they were flying.
As the altimeter error passed unnoticed by both pilots and because
they were not carrying out cross-checks of the two altimeters in
accordance with the relevant operations manual instruction attachment
No. 15, the error was not corrected by climbing to a safe altitude.
This disregard of the procedure laid down in the check lists and
operations manual for approach and landing may be explained by the
fact that the approach was carried out on a moonlight night in calm
weather and with visibility of approximatly 12nm, which reduced the
crew's concentration on precisely following the prescribed procedures
and checks. The visual effect of the runway slope made the situation
worse, giving the pilots a wrong impression of the aircraft's approach
angle. The co-pilot's alitmeter was found set at 1005,5 mb. The
difference between the QNH and QFE passed to the aircraft was
approximately equivalent to 1000ft. A figure which might have led to
further confusion."
