Analysis

According to the pilot's written statement, the pilot 'experienced [wind] shear on short final to runway 27...' A weather report for a reporting station located 21 nautical miles and 253 degrees from the accident site reported winds from 200 degrees at 11 knots. According to the 1999 Michigan Airport Directory, the runway that was used has several groupings of trees along both sides of the runway. Post accident investigation revealed damage to the right wing, propeller, nose landing gear, and fuselage substructure. Further examination revealed no pre-existing anomalies.
