On May 10, 2006, a Cessna 310C (registration N1788H) was involved in an aviation accident near Allentown, PA. Investigators recorded the probable cause as: The pilot neglected to lower the landing gear during the second landing attempt. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A pilot executed a go-around due to traffic, raised the landing gear, and on the subsequent approach neglected to lower it, resulting in the underside of the airplane contacting the ground. No mechanical deficiencies were found.
Event Sequence
The pilot made an initial approach to the runway. Due to traffic, a go-around was initiated. During the go-around, the landing gear was raised. The pilot then continued in the traffic pattern for another landing attempt.
Second Approach Incident
On the second approach, the pilot did not lower the landing gear. Consequently, the underside of the airplane made contact with the ground. The pilot reported that there were no mechanical deficiencies with the airplane.
Post-Event Examination
An FAA inspector examined the airplane and also found no mechanical deficiencies. The inspector's findings corroborated the pilot's report that the airplane had no issues.
Determination
The event occurred because the landing gear was not extended for the second landing. No mechanical factors were involved.
Probable cause
The pilot neglected to lower the landing gear during the second landing attempt.
