# NTSB DEN05CA050: Grumman G-1159, N74RQ, Logan, UT, January 20, 2005 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: January 19, 2005, 20:30 local (Jan 20, 2005, 03:30 UTC) - Place: Logan, UT - Coordinates: 41.788333, -111.853332 - Nearby events: https://openairdocs.org/map.md?lat=41.7883&lon=-111.8533&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 9 uninjured - Status: Completed, report March 30, 2005 - Report: Approved by Office Director - Parties: FAA Flight Standards District Office - NTSB case key (mKey): 60913 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DEN05CA050 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/60913/pdf - Page: https://openairdocs.org/ntsb/DEN05CA050 ## Probable cause the pilot's improper IFR operation by which he failed to comply to the missed approach procedure, and his improper evaluation of the weather resulting in an encounter with fog and his loss of visual contact with the runway during the landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight encounter with weather, landing - flare/touchdown - weather evaluation - inadequate, pilot in command (cause) - weather condition - fog (contributing factor) - visual lookout - inadequate, pilot in command - light condition - dark night (contributing factor) - ifr procedure - improper, pilot in command (cause) - missed approach - not performed, pilot in command (contributing factor) - Loss of control - on ground/water, landing - roll - directional control - not maintained, pilot in command (cause) - On ground/water encounter with terrain/water, landing - roll - terrain condition - snowbank (contributing factor) ## Analysis The captain stated they had flown the GPS approach to runway 35. When they did not see the runway or runway environment they initiated a missed approach. During the missed approach, they were able to see the first 4 to 5 thousand feet on the approach end of runway 17. They "elected to circle to the north west to set up for a visual approach to runway 17." The captain stated that the approach was "slightly high and as a result, the flare was a bit higher than normal." The airplane entered the fog layer just prior to touchdown. The captain stated that during the landing flare the airplane had drifted to the left and "the aircraft settled onto the runway to the left of centerline and shortly thereafter the left main gear impacted a snow berm." The airplane turned hard to the left and departed the runway. The nose gear separated, the radome was crushed and the cockpit pressure bulkhead was broken open. The routine aviation weather report (METAR) at LGU reported the weather as follows: wind, calm; visibility, 1/4 statute mile in freezing fog; sky condition, vertical visibility 100 feet agl; temperature, minus 7 degrees Celsius (C), dewpoint, minus 7 degrees C; altimeter, 30.45 inches. ## Factual narrative On January 19, 2005, approximately 2030 mountain standard time, a Grumman G-1159, N74RQ, operated by Icon Health and Fitness, was substantially damaged when it departed the runway and impacted a snow bank during landing roll at Logan-Cache Airport (LGU), Logan, Utah. Night instrument meteorological conditions prevailed at the time of the accident. The business flight was being conducted on an instrument flight rules flight plan under the provisions of Title 14 CFR Part 91. The airline transport certificated captain, first officer, and seven passengers reported no injuries. The cross-country flight originated at Kansas City (MKC), Missouri, approximately 1730. According to a written statement submitted by the captain, they had flown the GPS approach to runway 35. When they did not see the runway or runway environment they initiated a missed approach. During the missed approach procedure, they were able to see the first 4 to 5 thousand feet on the approach end of runway 17. They "elected to circle to the north west to set up for a visual approach to runway 17." The captain stated that the approach was "slightly high and as a result, the flare was a bit higher than normal." The airplane entered the fog layer just prior to touchdown. The captain stated that during the landing flare the airplane drifted to the left and "the aircraft settled onto the runway to the left of centerline and shortly thereafter the left main gear impacted a snow berm." The airplane turned hard to the left and departed the runway. The nose gear separated, the radome was crushed and the cockpit pressure bulkhead was compromised. An examination of the airplane's systems, conducted by the FAA, revealed no anomalies. The routine aviation weather report (METAR) at LGU reported the weather as follows: wind, calm; visibility, 1/4 statute mile in freezing fog; sky condition, vertical visibility 100 feet agl; temperature, minus 7 degrees Celsius (C), dewpoint, minus 7 degrees C; altimeter, 30.45 inches. ## Aircraft - Registration: [N74RQ](https://openairdocs.org/deregistered/N74RQ-2009-01-22), registration cancelled 2009-01-22, S/N 113, built 1972 (OpenAirDocs) - Reported make and model: Grumman G-1159 - Registry model: [Grumman G-1159](https://openairdocs.org/model/grumman-g-1159) (registry code 3953505) (OpenAirDocs) - Registry engine: [Rolls-Royce SPEY MK 511SR](https://openairdocs.org/engine/rolls-royce-spey-mk-511sr) (registry code 54523, turbo-jet) (OpenAirDocs) - Category: Airplane - Serial number: 113 - Airframe hours: 12011 - Engines: Rolls-Royce SPEY MKS11-8 11400 lbs thrust turbo jet; Rolls-Royce SPEY MKS11-8 11400 lbs thrust turbo jet - Damage: Substantial damage - Flight: Business, Part 91 - Registered owner: CFS Air LLC - Airworthiness certificate: Standard, Transport - Last inspection: AAIP, May 17, 2004, 225 hours before - Departed: MKC, KANSAS CITY, MO - Destination: LGU, Logan, UT - Flight plan: IFR - Airport: LGU, Logan-Cache Airport, runway 17, 9,095 × 100 ft, asphalt ## Flight crew As NTSB recorded them.
