Probable cause
the pilot's failure to maintain proper alignment on the taxiway. Factors associated with the accident were the fence post, and the sunglare, which hindered the pilot's ability to see the fence post.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During taxi after landing, the left wing of the airplane contacted a 6 inch diameter fence post at a position 4 feet inboard of the left wingtip. The post had been installed on a private taxiway as part of a gate to enclose a private hangar area. The post was located adjacent to the pavement as was another post on the other side of the taxiway. Clearance between the posts was 38 feet 5 inches. The airplane's wing span was 33 feet 6 inches. The pilot was unaware of the posts and was taxiing into the setting sun.
Factual narrative
On August 3, 1997, at 1930 central daylight time (cdt), a Beech A36, N4640M, operated by a commercial pilot collided with a steel post while taxiing after having landed at the Spirit of St. Louis Airport, Chesterfield, Missouri. The 14 CFR Part 91 flight was operating in visual meteorological conditions without a flight plan. The airplane received substantial damage to the left wing. The pilot and five passengers were not injured. The flight originated from Osage Beach, Missouri, at 1830 cdt.
The pilot was taxiing on a private taxiway when the left wing contacted a 6 inch diameter steel fence post which had recently been erected. The portion of the wing which contacted the post was about 4 feet inboard of the left wingtip.
The fence post had been installed as part of a gate to enclose a private hangar area. The fence post was located adjacent to the pavement as was another post on the other side of the taxiway. The clearance between the posts was 38 feet 5 inches. The wing span of N4640M was 33 feet 6 inches.
The pilot reported that the posts had been installed sometime after he had departed the airport on the previous day. He also stated that he was taxing into the setting sun which hindered his vision.
