Analysis 

The pilot reported that, during landing, the airplane encountered a gusting crosswind from the right. The airplane was configured with 0° flaps, and the airspeed was about 55 knots, and the airplane was about 5 ft above ground level. The airplane's airspeed was too slow for the gusting right crosswind conditions, and the airplane landed hard on the runway. The right main landing gear wheel separated from the airplane during the landing, and the airplane exited the runway to the right.

The airplane sustained substantial damage to the right main landing gear attachment points and the cabin's monocoque structure.

The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.

The METAR at the airport reported that, about the time of the accident, the wind was from 140° at 11 knots, gusting to 19 knots.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain adequate airspeed during landing in variable gusting crosswind conditions, which resulted in a hard landing and runway excursion.

Analysis

The flight instructor reported that the airplane’s fixed right main landing gear collapsed during landing. He reported that the landing was “not extraordinarily hard” and that it should have been well within the airplane’s typical performance.

Postincident examination of the composite right main landing gear leg revealed several manufacturing defects, including wrinkled layers and layers that terminated at the surface when they should have been continuous, which reduced the landing gear leg’s strength and its ability to resist longitudinal cracks. As a result of this investigation, the airplane manufacturer conducted an audit of the subcontractor that manufactured the landing gear legs. The audit revealed that, before the incident, the landing gear manufacturer had become aware of quality issues related to the mold closing process of the landing gear legs during manufacture and had implemented steps to reduce the recurrence of these issues. Based on the available evidence, the manufacturing defects in the composite main landing gear leg likely reduced the leg’s load-carrying capacity and resulted in its eventual failure. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this incident to be:
The manufacturing defects in the main landing gear leg, which resulted in its eventual failure.

Findings

Factual Information

On October 17, 2012, about 1330 eastern daylight time, a Flight Design GMBH model CTLS, N21ZA, sustained substantial damage while landing on runway 25 at the Lorain County Airport (LPR), Elyria, Ohio. The flight instructor and student pilot were not injured. The airplane sustained minor damage to the landing gear during the mishap. The aircraft was registered to RAS Aviation LLC, Elyria, Ohio, and operated by Zone Aviation, Elyria, Ohio, under the provisions of 14 Code of Federal Regulations Part 91 as an instructional flight. Visual meteorological conditions prevailed for the flight, which was not operated on a flight plan. The local flight originated at an unconfirmed time.

The flight instructor reported that the flight was a training flight and on the first landing the right main landing gear collapsed. He stated that the landing was "not extraordinarily hard". He went on to add that based on his experience in the same model airplane that the landing should have been well within typical performance of the airplane.

During the investigation it was discovered that this same airplane was involved in a landing accident on July 19, 2012 (CEN12LA676). The July accident also resulted in a fracture of the right main landing gear leg.

The damaged right main landing gear leg from this incident was retained for further examination.  The main landing gear leg was made of composite material. The fiber reinforcements used in the composite construction included unidirectional glass fibers, glass fiber fabric, and basalt fiber fabric. Flexible plastic tubes extended the length of the legs enclosed within ribbed plastic tubes located near the leading and trailing edges of the leg. Foam filled space between the plastic tubes and a center internal cavity. The legs were manufactured in a mold with the split line at the leading and trailing edges. During the layup process, layers were placed in a mold half representing the upper half of the leg, and layers were wrapped around the internal tubes, foam, center cavity, and preformed layers. The mold was then closed with a mold piece representing the lower half of the landing gear, and the center internal cavity was pressurized during curing. Examination and sectioning of the landing gear leg showed wrinkling of the fibers resulting in their orientation being angled with relation to the surface rather than parallel to the surface. Additionally several layers terminated at the leading and trailing edges. The location of theses terminating layers corresponded with the location of longitudinal cracks found along the leading and trailing edges of the landing gear.

As a result of the investigation, the manufacturer of the airplane was contacted regarding the landing gear manufacturing process. The landing gear legs were manufactured by a sub-contractor to the airplane manufacturer. The airplane manufacture conducted an audit of the sub-contractor and determined that there were some previous quality issues with regard to mold closing during the manufacture of the landing gear legs. It was reported that the landing gear manufacturer had recognized these issues and had implemented steps to reduce the risk of recurrence of these issues. The airplane manufacturer also conducted a search of part requests and difficulty reports related to the main landing gear. This records search showed 3 occurrences which resulted in complete collapse of the landing gear leg out of a fleet of 370 airplanes. All other reported landing gear leg fractures were discovered either during inspection after a hard landing, or during taxi operation when significantly reduced stiffness was encountered.

Analysis

The pilot reported that, on the day of the accident, he had accomplished three landings in the accident airplane and that he was pleased with these landings. Forty-five minutes after the last day landing, he took off for a night flight. During the first attempted landing, he misjudged the flare, and the airplane bounced. He subsequently performed a go-around and again misjudged the landing flare. The airplane subsequently bounced hard on the runway, which resulted in a flat nosewheel tire and firewall and right main landing gear damage. Although examination of the right main landing gear leg revealed several manufacturing defects that have since been addressed by the landing gear leg manufacturer, the accident was likely caused by the pilot’s misjudged landing flare, which resulted in a hard landing and the subsequent right main landing gear damage.

Probable Cause and Findings

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

The pilot’s misjudged landing flare, which resulted in a hard landing.

Factual Information

On July 19, 2012, about 2200 eastern daylight time, a Flight Design GMBH model CTLS, N21ZA, sustained substantial damage while landing on runway 7 at the Lorain County Airport (LPR), Elyria, Ohio. The private pilot who was the sole occupant was not injured. The airplane sustained damage to the landing gear, engine mount and firewall during the mishap. The aircraft was registered to RAS Aviation LLC, Elyria, Ohio, and operated by Zone Aviation, Elyria, Ohio, under the provisions of 14 Code of Federal Regulations Part 91. The airplane was rented by the pilot for a personal flight. Visual meteorological conditions prevailed for the flight, which was not operated on a flight plan. The local flight originated at an unconfirmed time.

The accident was not initially reported to authorities and was discovered while investigating another incident that happened with this airplane. On October 17, 2012, about 1330 the airplane sustained minor damage while landing on runway 25 at LPR (CEN13IA024). In both instances, the right composite landing gear leg fractured. 

Regarding the July accident, the pilot reported that he was performing takeoff and landing practice. He performed 3 landings during the daylight and he reported that he was pleased with these landings.  After a 45 minute break he took off again to perform night landings to regain night currency requirements. He reported that on the first night landing he misjudged the landing and bounced. He performed a go-around and came back in for another landing. He again misjudged the landing and "bounced hard". The airplane came back down striking the nose wheel. As the airplane came to a stop the pilot realized there was something wrong and upon de-planing, discovered a flat nose tire. He pushed the airplane from the runway and acquired a tow from ramp personnel.

The damaged right main landing gear leg was retained for further examination.  The main landing gear leg was made of composite material. The fiber reinforcements used in the composite construction included unidirectional glass fibers, glass fiber fabric, and basalt fiber fabric. Flexible plastic tubes extended the length of the legs enclosed within ribbed plastic tubes located near the leading and trailing edges of the leg. Foam filled space between the plastic tubes and a center internal cavity. The legs were manufactured in a mold with the split line at the leading and trailing edges. During the layup process, layers were placed in a mold half representing the upper half of the leg, and layers were wrapped around the internal tubes, foam, center cavity, and preformed layers. The mold was then closed with a mold piece representing the lower half of the landing gear, and the center internal cavity was pressurized during curing.

Defining Event: Loss of control in flight
Injuries: 1 Minor, 1 None
Flight Conducted Under: Part 91: General Aviation - Personal 

On September 16, 2018, at 1606 eastern daylight time, a Cirrus SR22, N161DL, was substantially damaged during collision with trees and terrain during takeoff from Montauk Airport (MTP), Montauk, New York. The pilot was not injured, and a passenger sustained minor injuries. Visual meteorological conditions prevailed, and no flight plan was filed for the personal flight, which was conducted under the provisions of Title 14 Code of Federal Regulations Part 91.

The pilot provided a written statement and was interviewed by telephone. He said he completed the preflight inspection, engine run-up, and before-takeoff checks with no anomalies noted, and then positioned the airplane for takeoff from runway 24. The pilot advanced the throttle and tracked the runway centerline during the takeoff roll.

At rotation, the pilot's seat "abruptly slid backwards to the outermost distance from the controls." The pilot said that he could no longer reach the pedals to maintain directional control, and that aileron input was inadequate to counteract the airplane's left-turning tendency. The airplane departed the left side of the runway, struck trees and shrubs, and came to rest upright. According to the pilot, except for the pilot seat, the airplane performed as designed with no other anomalies noted.

The pilot stated that he had adjusted his seat prior to the flight "as normal" and had never had difficulty with the seat at any time in the past. He added that this was the third Cirrus SR22 that he had owned and had no history of seat issues with either of his previous two airplanes.

The pilot held a private pilot certificate with ratings for airplane single engine land and instrument airplane. His most recent Federal Aviation Administration (FAA) third class medical certificate was issued January 4, 2018. He reported 750 total hours of flight experience, all of which was in the accident airplane make and model.

According to FAA records, the airplane was manufactured in 2014. Its most recent annual inspection was completed October 15, 2017 at 187.9 total aircraft hours.

At 1654, the weather recorded at MTP included clear skies and variable winds at 4 knots. The temperature was 24°C, and the dew point was 19°C. The altimeter setting was 30.21 inches of mercury.

Examination of photographs revealed that the wings, fuselage, and empennage all sustained substantial impact damage. An FAA inspector who responded to the site said he could not enter the cockpit, as the door was either locked or impinged by impact damage.

Examination of the pilot's seat was performed by a manufacturer's representative under the supervision of an NTSB air safety investigator, and cabin safety specialist.

The examination revealed no anomalies with the installation, dimensions, or operation of the pilot's seat. The seat moved freely fore and aft, with no binding or anomalous operation noted. While seated in the pilot's seat, the manufacturer's representative applied fore, aft, and twisting forces to the seat to "unlock" the seat from a locked position. When "twisted to right while being slid forward" partial seat position locking pin engagement could be induced, but not all pins would seat and the control handle would not be fully down, and neither could it be forced into position. Straightening or forward movement of the seat resulted in full pin engagement with the control handle in the fully-down position.

According to the Pilot Operating Handbook and the placard on the center console, "CREW SEATS MUST BE LOCKED IN POSITION AND CONTROL HANDLES FULLY DOWN BEFORE FLIGHT"

Flight Conducted Under: Part 91: General Aviation - Personal 

On September 16, 2018, at 1606 eastern daylight time, a Cirrus SR22, N161DL, was substantially damaged during collision with trees and terrain during takeoff from Montauk Airport (MTP), Montauk, New York. The pilot was not injured, and a passenger sustained minor injuries. Visual meteorological conditions prevailed, and no flight plan was filed for the personal flight, which was conducted under the provisions of Title 14 Code of Federal Regulations Part 91.

The pilot provided a written statement and was interviewed by telephone. He said he completed the preflight inspection, engine run-up, and before-takeoff checks with no anomalies noted, and then positioned the airplane for takeoff from runway 24. The pilot advanced the throttle and tracked the runway centerline during the takeoff roll.

At rotation, the pilot's seat "abruptly slid backwards to the outermost distance from the controls." The pilot said that he could no longer reach the pedals to maintain directional control, and that aileron input was inadequate to counteract the airplane's left-turning tendency. The airplane departed the left side of the runway, struck trees and shrubs, and came to rest upright.

The pilot stated that he had adjusted his seat prior to the flight "as normal" and had never had difficulty with the seat at any time in the past. He added that this was the third Cirrus SR22 that he had owned and had no history of seat issues with either of his previous two airplanes.

The pilot held a private pilot certificate with ratings for airplane single engine land and instrument airplane. His most recent Federal Aviation Administration (FAA) third class medical certificate was issued January 4, 2018. He reported 750 total hours of flight experience, all of which was in the accident airplane make and model.

According to FAA records, the airplane was manufactured in 2014. Its most recent annual inspection was completed October 15, 2017 at 187.9 total aircraft hours.

At 1654, the weather recorded at MTP included clear skies and variable winds at 4 knots. The temperature was 24°C, and the dew point was 19°C. The altimeter setting was 30.21 inches of mercury.

Examination of photographs revealed that the wings, fuselage, and empennage all sustained substantial impact damage. An FAA inspector who responded to the site said he could not enter the cockpit, as the door was either locked or impinged by impact damage.

The airplane was retained for further examination.
