Circumstances:
The aircraft departed Lima-Jorge Chávez Airport at 0042LT on an international regular service to Santiago de Chile, carrying 61 passengers and a crew of nine. When they took off and reached speed V2 + 10, the crew noticed that the altimeters were not responding and that something irregular was occurring. They therefore decided to notify the control tower in Lima to declare an emergency, consulted Lima for confirmation of their altitude by radar, and requested assistance to return via radar vectors. After 29 minutes of flight, while returning to Lima airport and with the crew attempting to control the aircraft, it impacted with the sea 48 nautical miles from the airport, with the total loss of the aircraft and all of its occupants.
Probable cause:
The following findings were reported:
- It can be deduced from the investigation carried out that the maintenance staff did not remove the protective adhesive tape from the static ports. This tape was not detected during the various phases of the aircraft's release to the line mechanic, its transfer to the passenger boarding apron and, lastly, the inspection by the crew responsible for the flight (the walk-around or pre-flight check), which was carried out by the pilot-in-command, according to the mechanic responsible for the aircraft on the day of the accident.
- The pilot-in-command made a personal error by not complying with the procedure for GPWS alarms and not noticing the readings of the radio altimeters in order to discard everything which he believed to be fictitious.
- The copilot made a personal error by not being more insistent, assertive and convincing in alerting the pilot-in-command much more emphatically to the ground proximity alarms.

On March 9, 1996, a De Havilland DHC-6-200, N245GW, registered to Air Associates Inc., leased to Carson Services Inc., operating as a 14 CFR part 91 aerial survey flight, crashed at an undetermined time. Visual meteorological conditions prevailed at the departure airport, and no flight plan was filed. The airplane is missing and is presumed destroyed. The American pilot-in-command, American survey operator, and Peruvian Air Force observer are missing, and are presumed to be fatally injured. The flight originated from Bagua, Peru, at about 0617 mountain daylight time. Personnel from the Director General of Civil Aviation stated, the airplane departed from Bagua, Peru, conducting an aerial geological survey near the disputed boarder with Ecuador, in the Cenepa River area over dense Amazon jungle. The airplane did not return to Bagua, and there are no known recorded radio communications with N245GW. Search and rescue operations have been uneventful.

Circumstances:
The approach to Arequipa-Rodríguez Ballón Airport was completed by night and poor weather conditions with heavy rain falls. On final approach, the crew failed to realize his altitude was insufficient when the aircraft struck a hill and crashed 6,3 km from runway 09 threshold. The aircraft disintegrated on impact and all 123 occupants were killed.
Probable cause:
Controlled flight into terrain. It was reported that during his last communication with ATC, the pilot reported his altitude at 9,500 feet while the real altitude of the aircraft was 8,644 feet. It is believed that the accident may have been caused by an altimeter misreading or a wrong altimeter setting. The lack of visibility was considered as a contributing factor.

Probable cause:
Wrong approach configuration on part of the crew who landed too far down the runway, reducing the landing distance available.
