Probable cause
The pilot's inability to maintain directional control due to an obstruction of the left brake line by foreign material resulting in asymmetrical braking.
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
The pilot of the tail wheel equipped Andelin (Pitts) S1E reported that after a local flight he returned to his airport of departure and set up for an approach to runway 25. He made a 3-point touchdown and as the aircraft decelerated through about 40 miles per hour the aircraft began to drift right of centerline. The pilot attempted to correct with the application of left rudder but the aircraft continued to the right at which time he applied left brake. The aircraft's lower left wingtip then contacted the runway and the aircraft decelerated to a stop coming to rest on its nose and right wingtip. Post-crash examination of the aircraft's braking system revealed a piece of hose lining material within the left brake line at the caliper fitting which completely obstructed the left brake line. This condition would have resulted in asymmetrical braking.
Factual narrative
On July 16, 2003, approximately 1615 Pacific daylight time, a tail wheel equipped Andelin (Pitts) S1E experimental aircraft, N732E, registered to and being flown by an airline transport rated pilot, sustained substantial damage during a loss of control and nose down event during the landing roll at the Portland-Troutdale airport, Troutdale, Oregon. The pilot was uninjured. Visual meteorological conditions prevailed and no flight plan had been filed. The flight, which was personal, was operated under 14 CFR 91, and originated from Troutdale, earlier in the afternoon.
The pilot reported that after a local flight he returned and set up for an approach to runway 25 at he Troutdale airport. He made a 3-point touchdown and as the aircraft decelerated through about 40 miles per hour the aircraft began to drift right of centerline. The pilot reported that he applied left rudder but the aircraft continued to the right at which time he applied left brake. The aircraft's lower left wingtip contacted the runway. The aircraft decelerated to a stop coming to rest on its nose and right wingtip.
The pilot reported that the Troutdale air traffic control tower advised of variable winds at six knots. The 1653 surface weather observation taken at Troutdale airport reported winds as variable at three knots.
Post-crash examination of the aircraft's braking system revealed a piece of hose lining material within the left brake line at the caliper fitting which completely obstructed the left brake line (refer to Attachment M-I and photograph 1).
