# NTSB MIA07CA115: Mooney M20R, N321MD, Mitchellville, MD, July 1, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: July 1, 2007, 17:30 local (21:30 UTC) - Place: Mitchellville, MD - Coordinates: 38.9411111111111, -76.7722222222222 - Nearby events: https://openairdocs.org/map.md?lat=38.9411&lon=-76.7722&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 3 uninjured - Status: Completed, report October 31, 2007 - Report: Approved by Office Director - NTSB case key (mKey): 66134 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA07CA115 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/66134/pdf - Page: https://openairdocs.org/ntsb/MIA07CA115 ## Probable cause The pilot's failure to attain the proper touchdown point for landing and his failure to initiate a go-around when he realized the airplane would touchdown past the intended point. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - roll - proper touchdown point - not attained, pilot in command (cause) - go-around - not performed, pilot in command (cause) - On ground/water encounter with terrain/water, landing - terrain condition - berm ## Analysis The pilot stated that the airplane was on the glide path and approach speed was approximately 85 knots. Several minutes prior, the manifold pressure gauge became erratic and was unable to be used as an accurate indication. He pushed the manifold control full forward for the remainder of the approach. The landing touchdown was 1/3 down the runway and seemed to be a "tad fast". Halfway down the runway, he realized the engine wasn't going completely to idle. At about 2/3 down the runway, knowing that the airplane was too fast, he looked at the option of going around and ruled it out because of the slow speed and the height needed to clear the tree line. He attempted to slow the airplane by applying full brakes; however, was unable to slow down before running off the runway. The pilot stated to the NTSB investigator that there were no mechanical issues with the airplane and he should have initiated a go-around. The published length of runway 18/36 at the Freeway Airport, Mitchellville, Maryland, is 2,420 feet by 40 feet. ## Factual narrative The pilot stated the approach was on the glide path and approach speed was approximately 85 knots. Several minutes prior, the manifold pressure gauge became erratic and was unable to be used as an accurate indication. He pushed the manifold full forward for the remained of the approach. The landing touchdown was 1/3 down the runway and seemed to be a "tad fast". Halfway down the runway, he realized the engine wasn't going completely to idle. At about 2/3 down the runway, knowing that the airplane was too fast, he looked at the option of going around and ruled it out because of the slow speed and the height needed to clear the tree lines. He attempted to slow the airplane by applying full breaks; however, was unable to slow down before running off the runway. The responding FAA inspector observed the accident airplane lying off a berm, in a nose down position, approximately 50 yards from the end of the runway. The damage consisted of a bent propeller, buckled nose gear, damage to main gear doors, wrinkling of the right wing between station 147.75 and 163 and damage to the wing spar, and a dent in the leading edge of the right horizontal stabilizer. The pilot stated to the NTSB investigator that there were no mechanical issues with the airplane and he should have initiated a go around. The published length of runway 18/36 at the Freeway Airport, Mitchellville, Maryland, is 2,420 feet by 40 feet. A completed Pilot/Operator Aircraft Accident/ Incident Report was not received for this accident. ## Aircraft - Registration: [N321MD](https://openairdocs.org/aircraft/N321MD), registered now, S/N 29-0470, built 2006 (OpenAirDocs) - Reported make and model: Mooney M20R - Registry model: [Mooney M20R](https://openairdocs.org/model/mooney-m20r) (registry code 5870225) (OpenAirDocs) - Registry engine: [Continental IO-550-G](https://openairdocs.org/engine/continental-io-550-g) (registry code 17213, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 29-0470 - Engines: Teledyne Continental IO-550-G reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Gregory S.

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.
