NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The private pilot/owner seated in the right seat was type rated in the airplane. The second pilot in the left seat manipulating the flight controls, held an ATP and flight instructor certificates, but was not type rated in the airplane. The second pilot had a total of 1.9 hours in the airplane. Both pilots stated that they selected runway 3 for landing based on weather reports and that other airplanes were using that runway. During landing rollout, propeller reverse power was selected and the left engine came in before the right engine, which caused the airplane to veer left, and braking was used to correct the heading. The propellers were brought out of reverse and the airplane continued to exit the left side of the runway and collapsed the nose gear. The manager of the FBO said they were advising runway 21 as the active runway. The pilot of another airplane said that he had just landed on runway 21 and that there were two other airplanes in the traffic pattern for runway 21 when the accident airplane landed on runway 3. He stated that winds were 130 degrees at 14 knots and the conditions in the pattern were turbulent. The pilot noted that after he landed the wind kept shifting direction from a southeasterly to northeasterly heading. No mechanical anomalies were found during an examination of the propeller reverse system or the braking system.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot in command's selection of the wrong runway for the prevailing wind conditions, and the second pilot's inadequate compensation for the winds. Factors in the accident were the second pilot's lack of experience in the aircraft and the pilot-in-command's inadequate supervision of the flight. Additional factors were the variable and gusty, cross wind and tail wind conditions.
