# NTSB FTW97LA367: Beech 58, N365C, Mora, NM, September 28, 1997 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: September 28, 1997, 07:30 local (13:30 UTC) - Place: Mora, NM - Coordinates: 35.970211, -105.319038 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=35.9702&lon=-105.3190&mi=10 - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 2 serious - Status: Completed, report June 26, 1998 - Report: Approved by Office Director - NTSB case key (mKey): 20359 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW97LA367 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/20359/pdf - Page: https://openairdocs.org/ntsb/FTW97LA367 ## Probable cause loss of power in the right engine for undetermined reason(s). Related factors were: that the power loss occurred above the airplane's single engine service ceiling (at high density altitude), and the lack of suitable terrain for a forced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(partial) - nonmechanical, climb - to cruise - 1 engine - reason for occurrence undetermined (cause) - Forced landing, emergency descent/landing - weather condition - high density altitude (contributing factor) - aircraft performance,engine out capability (contributing factor) - On ground/water encounter with terrain/water, emergency landing - terrain condition - none suitable (contributing factor) - terrain condition - rock(s)/boulder(s) (contributing factor) ## Analysis As the pilot stepped climbed the airplane through 12,000 feet, the right engine lost power. The power loss was confirmed by low manifold and fuel pressures. Activation of the boost pump increased fuel flow, but did not restore power. Despite full power from the left engine and the propeller set at fine pitch, the airplane was unable to maintain altitude. The pilot elected not to feather the right propeller because this would cause the airplane to descend to single engine service ceiling, and since the right engine manifold pressure indicated some power was being developed, he elected to make a forced landing in an open meadow. The airplane slid across the ground, struck a large rock, and spun around; then a fire erupted. Disassembly and inspection of the right engine failed to disclose any discrepancy that would have been causal to the power loss. Most engine accessories were destroyed by postimpact fire. ## Factual narrative On September 28, 1997, approximately 0730 mountain daylight time, a Beech 58, N365C, operated by Cutter Aviation, Inc., doing business as Cutter Flying Service, Inc., was destroyed by impact forces and postimpact fire when it collided with terrain near Mora, New Mexico, approximately 24 miles northeast of Santa Fe, New Mexico, in the Pecos National Forest and Wilderness Area. The airline transport rated pilot and one passenger sustained serious injuries. Visual meteorological conditions prevailed, and a company VFR flight plan had been filed for the nonscheduled domestic passenger air taxi flight being conducted under Title 14 CFR Part 135. The flight originated at Albuquerque approximately 0650. In his accident report, the pilot said he performed a complete preflight inspection of the airplane, and noted the fuel tanks were full and fuel samples drained were clear. He obtained a weather briefing, computed a weight and balance, and gave his passenger a thorough safety briefing. After takeoff, the pilot climbed to 9,500 feet, then "step climbed" as the terrain rose to "avoid oxygen deprivation and comply with FARs." As the airplane passed through 12,000 feet, the right engine lost power. The pilot said he confirmed this by noting low manifold and fuel pressures. When he switched the right engine boost pump on, there was an increase in fuel flow, but full power was not restored. The pilot said that despite the left engine developing full power and the propeller set at fine pitch, the airplane was unable to maintain altitude. He also said if he feathered the right propeller, the airplane would descend to single engine service ceiling and since the right engine manifold pressure indicated some power being developed, he elected to make a landing in an open meadow. The pilot extended approach flaps and lowered the landing gear, but he did not believe the landing gear extended fully before the airplane contacted the ground. According to an FAA inspector who went to the scene, the airplane slid across the ground and struck a large rock with its right wing, turning the airplane 90 degrees to the right. The airplane then caught fire. The two occupants exited the airplane via the cabin door over the right wing. The passenger corroborated the pilot's report. He added that it was a beautiful day and the pilot was step climbing the airplane to provide him a better view of the landscape. The passenger added he was an avid hunter. Disassembly and inspection of the right engine failed to disclose any discrepancies that would have been causal to the loss of power. Most of the engine accessories were destroyed in the postimpact fire. The single engine service ceiling of the Beech 58 at maximum gross weight is 7,000 feet. ## Aircraft - Registration: [N365C](https://openairdocs.org/deregistered/N365C-1998-02-27), registration cancelled 1998-02-27, S/N TH346 (OpenAirDocs) - Reported make and model: Beech 58 - Registry model: [Beech 58](https://openairdocs.org/model/beech-58) (registry code 1152740) (OpenAirDocs) - Category: Airplane - Serial number: TH346 - Airframe hours: 3878 - Engines: Continental IO-520-CB 285 horsepower reciprocating - Damage: Destroyed - Fire: On-Ground - Flight: Part 135 - Operator: Cutter Aviation, doing business as Cutter Flying Service, Inc. - Registered owner: Cutter Aviation, Inc - Airworthiness certificate: Standard, Normal - Last inspection: AAIP, September 9, 1997, 10 hours before - Departed: ABQ, ALBUQUERQUE, NM - Destination: LHX, LA JUNTA, CO - Flight plan: Company VFR ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
