LANSA flight 501 was a scheduled domestic flight operated by the Peruvian airline Líneas Aéreas Nacionales SA (LANSA) on April 27, 1966. The machine used was of the Lockheed Constellation L-749 type ( aircraft registration number : OB-R-771).
background
The Lockheed Constellation L-749 was built on May 27, 1947 and was previously in service with Eastern Air Lines , Great Lakes Airlines , Admiral Airways , California Hawaiian Airlines and Trans California Airlines .
The pilot in command ( pilot in charge) has already flown this route 112 times.
Flight history
The Constellation took off from Runway 15 at Lima Airport at 7:40 a.m. on Wednesday, April 27, 1966. After 25 minutes, it struck Mount Talaula at an altitude of 3,840 meters (12,600 feet ) , 54 kilometers (29 NM ) north of the planned flight route and 113 kilometers (61 NM) east of the take-off airport.
examination
The Accident Commission came to the conclusion that the crash was due to pilot failure:
a) Deviation from the predetermined flight route
b) resulting in incorrect calculation of the rate of climb . With a takeoff weight of 41,083 kg (90.572 lbs ), flying over this ridge was not possible.
c) incorrect assessment of the heights of the mountains to be flown over or around on this deviating flight route.
d) During 112 flights on this route, the Accident Commission suspected that the pilot in command (pilot in command) was either overtired or insufficiently rested, as he was not actually registered for this flight. He may have been fooled by the perfect weather that morning and chose a different, more direct route.
e) Ultimately, the possibility of a technical failure of the aircraft was not completely ruled out, even if this could actually be ruled out in view of the perfect weather conditions and the alternative routes, including around the mountain or the crash site, and possibly such a flight route with this impact location and altitude not explained.
