Location: Cleburne, TX
Accident Number:CEN19LA159 
Date & Time: 05/30/2019, 1100 CDT
Registration: N2514F
Aircraft: Lancair LC41
Aircraft Damage: Substantial
Defining Event: Powerplant sys/comp malf/fail
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Business 

On May 30, 2019, about 1100 central daylight time, a Lancair LC41 airplane, N2514F, conducted a forced landing near the Cleburne Regional Airport (CPT), Cleburne, Texas. The pilot was not injured, and the airplane sustained substantial damage. The airplane was registered to and operated by Van Bortel Aircraft, Inc under the provisions of Title 14 Code of Federal Regulations Part 91 as a maintenance test flight. Visual meteorological conditions prevailed for the local flight at the time of the accident.

The flight was conducted to break-in the engine's No. 5 cylinder, which had just been replaced. During the flight, the pilot noticed the oil pressure warning light illuminate, followed by a low oil temperature indication. The pilot attempted to divert to CPT; however, the engine experienced a loss of power and he conducted a forced landing. During the landing, the airplane collided with trees and came to rest upright and partly submerged in a small pond about one mile from CPT.

Inspection of the airplane revealed substantial damage to the wings, and water submersion damage to the airplane. The airplane's Hobbs meter read 1,090.1 hours.

The airplane was recovered to a secure facility for further examination. The examination was conducted by the NTSB Investigator-in-Charge, a representative from Van Bortel Aircraft, and technical representatives from the engine and airframe manufacturers. The examination noted the engine case had a hole above the No. 4 cylinder, and when the propeller was rotated by hand, the engine had limited rotation and internal binding was noted. A light, oil film was noted on the bottom of the airplane. The exam also found an oil pressure switch separated in two pieces. The threaded section remained to its mating joint; the other section rested on an exhaust tube and attached by its wire connector as seen in Figure 1.

A visual inspection of the switch noted that the switch had separated at a manufacturing joint between the body and threaded section.

The switch was removed and sent to Textron Aviation, Inc, Materials Laboratory for a detailed examination of the switch. Textron's examination noted the switch failed at the swaged joint between the threaded section and the base cap section of the switch. The examination was not able to determine how the joint failed, since there were no physical indications as to how the swaged joint failed.

A pilot walked away without any serious injury after an emergency landing north of Cleburne on Thursday.

The pilot took off from Arlington Municipal Airport in a Lancair LC41-550FG but detected an oil pressure problem once he was airborne, according to authorities.

The pilot declared mayday due to the loss of oil pressure and a loss of engine power and attempted a landing at Cleburne Regional Airport, a statement from the Federal Aviation Administration said.

After seeing the plane was not going to be able to make it to the airport, the pilot attempted to make a landing in a field near East Industrial Boulevard and U.S. 174, according to authorities.

The aircraft hit some trees during the emergency landing attempt and came to rest in a small stock pond about four miles northeast of Cleburne Airport, the statement said.

The pilot was unhurt, according to the Johnson County office of emergency management.

A pilot managed to exit safely and avoid injury after his Lancair LC41-550FG crash landed.

The accident occurred shortly after 11 a.m. today in a small pond in a wooded area about a quarter of a mile off County Road 701 in Cleburne.

Initial radio reports indicated that the plane was in the water right side up with the pilot standing on the wing. No other passengers were in the plane.

Cleburne police and firefighters responded to the scene, as did troopers from the Texas Department of Public Safety. Rescue workers initially experienced difficulty finding the site.

One rescue worker on scene commented that it’s fortunate that the plane landed the way it did and avoided nearby trees and power lines.

The pilot declined to give his name and said he did not wish to discuss the accident until he spoke with FAA representatives. The pilot, who said he was fine, said he used a flotation seat to get to shore because he feared there may be snakes in the water.

One officer on scene said the partially submerged plane will be floated up then pulled from the pond after which the wings will be removed and the plane transported.

Officers on scene said the cause of the accident remains under investigation.
