# NTSB CHI08CA163: Mooney M20K, N252AD, New Philadelphi, OH, June 14, 2008 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: June 14, 2008, 14:30 local (18:30 UTC) - Place: New Philadelphi, OH - Coordinates: 40.470832, -81.419723 - Nearby events: https://openairdocs.org/map.md?lat=40.4708&lon=-81.4197&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Defining event: [Landing-flare/touchdown: Landing gear not configured](https://openairdocs.org/ntsb-events/095) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report July 30, 2008 - Report: Approved by Office Director - Parties: Federal Aviation Administration, Cleveland FSDO - NTSB case key (mKey): 68261 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI08CA163 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/68261/pdf - Page: https://openairdocs.org/ntsb/CHI08CA163 ## Probable cause The pilot's failure to extend the landing gear prior to landing. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Action: lack of action](https://openairdocs.org/ntsb-findings/02041030): Personnel issues › Action/decision · Pilot (probable cause); cases with it: [Mooney M20K, 1 case](https://openairdocs.org/ntsb-findings/02041030/cases.md?model=5870220), [All aircraft, 792 cases](https://openairdocs.org/ntsb-findings/02041030/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight. The defining event best describes what happened. - [Landing-flare/touchdown: Landing gear not configured](https://openairdocs.org/ntsb-events/095) (defining event); cases with it: [Mooney M20K, 6 cases](https://openairdocs.org/ntsb-events/095/sequence.md?model=5870220), [All aircraft, 584 cases](https://openairdocs.org/ntsb-events/095/sequence.md) ## Analysis The pilot thought he had lowered the landing gear at the final approach fix, but "did not check it down and locked." The airplane was traveling faster than normal as it crossed over the runway threshold, and it ballooned during the landing flare. The pilot heard the audible gear warning say "check gear" as he was reaching to increase the throttle for a go-around. He was reaching for the landing gear handle as the airplane settled onto the runway. The airplane slid about 850 feet before coming to rest. The lower fuselage skin and its corresponding substructure were damaged during the wheels-up landing. The pilot said the accident could have been prevented if he had verified the position of the landing gear prior to landing. He also said that he was distracted during the approach with changing radio frequencies, and correcting for being high and fast on the approach. ## Factual narrative The pilot thought he had lowered the landing gear at the final approach fix, but "did not check it down and locked."

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.
