Calibration

The crew was engaged in a check of the Lubbock Airport facilities. During the takeoff roll, the airplane became uncontrollable, veered off runway and came to rest with its undercarriage raised. All three crew members were uninjured while the aircraft was damaged beyond repair.

A Federal Aviation Administration Douglas C-47, N7, crashed approximately 2,000 feet short of the approach threshold of runway 06 at LaGuardia Airport, New York. The crew was attempting to fly an Instrument Landing System approach in instrument meteorological conditions at night. The LaGuardia weather reported 3 minutes after the accident was: '200 feet scattered, measured 300 broken, 600 overcast, visibility 1 1/2 mile, light rain, fog, wind 060° at 11 knots, altimeter 29.63 inches, runway 04, visibility variable to 3 miles.

On final approach to Husum Airport, while completing a calibration flight from Westerland, the airplane stalled and crashed in a field located few hundred meters short of runway. All four crew members were killed.

The crew was performing a calibration flight at tachikawa AFB, Tokyo. On touchdown, the undercarriage collapsed and the airplane slid for several yards before coming to rest on the runway. While all five crew members were uninjured, the aircraft was damaged beyond repair.

The crew was performant the calibration of the ILS system at Pittsburgh-Greater Pittsburgh Airport. While approaching from the northeast, the engine stopped. The airplane lost height, struck trees and crashed in Coraopolis, some 3 miles northeast of the airfield. All three crew members were injured and the aircraft was destroyed.

The crew was engaged in the calibration of the Tehran-Mehrabad International Airport ILS system. While approaching the airport from the northwest, the crew encountered poor visibility due to heavy rain falls. The twin engine aircraft struck the slope of a mountain shrouded in clouds and located near the locality of Khozankala, about 33 km northwest of the airport. The aircraft was destroyed and all four crew members were killed. The wreckage was found near the Amir Kabir Dam.

Operated by the Department of Transport, the aircraft was engaged in a calibration flight at Saint-Jean-sur-Richelieu Airport, Quebec. While in initial climb, the left engine failed, followed shortly later by the right engine. The crew attempted a belly landing in a field near the airport. The aircraft came to rest and was written off while all three occupants were uninjured.

The aircraft, a trainer conversion of a B-29 four engine bomber, and its crew were with the 5040th Radar Evaluation Squadron based at Elmendorf Air Force Base near Anchorage. On this day, they were on a routine radar-calibration training mission that was to last about 10 hours. Flying south down the Susitna Valley in bad weather, however, they strayed 27 miles off course into the Talkeetna Mountains. At 1822LT, the aircraft crashed into an unnamed glacier at an altitude of 5,600 feet and some 39 miles southeast of Talkeetna, just northeast of the Hatcher Pass. Six crew were killed while four others were injured.

Owned by the Ministry of Civil Aviation, the twin engine aircraft was involved in a calibration flight on behalf of the Civil Aviation Authority and was carrying two inspectors from the CAA and two crew members. They were performing a calibration of the ILS system at Gatwick Airport when the airplane crashed in unknown circumstances in the city of Petersfield, about 33 miles southwest of Gatwick. All four occupants were killed.

The aircraft was engaged in a flight from Mount Hagen to Madang with stops scheduled in Ogelbeng, Tremearne, Baiyer River, Wabag, Wapenamanda and Yarramunda, carrying two inspectors from the DCA and one pilot who were performing inspections of various local airfields. While flying in a narrow valley, the pilot elected to gain height when the aircraft hit trees and crashed in flames. The airplane was destroyed by a post crash fire and all three occupants were killed.
