Location: Fort Wayne, IN
Accident Number: CEN17LA144
Date & Time: 03/29/2017, 2156 EDT
Registration: N580PU
Aircraft: CIRRUS DESIGN CORP SR20
Aircraft Damage: Destroyed
Defining Event: Loss of control in flight
Injuries: 1 Serious, 1 Minor
Flight Conducted Under: Part 91: General Aviation - Instructional 

On March 29, 2017, about 2156 eastern daylight time, a Cirrus SR-20, N580PU, was destroyed when it impacted the ground following a loss of control while landing on runway 5 at the Fort Wayne International Airport (FWA), Fort Wayne, Indiana. The flight instructor received minor injuries and the pilot receiving instruction received serious injuries. The pilot receiving instruction held a private pilot certificate. The airplane received extensive damage to the forward fuselage and both wings. The aircraft was registered to the Trustees of Purdue University and operated by the University under the provisions of 14 Code of Federal Regulations Part 91 as an instructional flight. Visual meteorological conditions prevailed for the instructional flight, which operated on a visual flight rules flight plan. The flight originated from the Purdue University Airport (LAF), Lafayette, Indiana about 2100. The intended route of flight would have returned to LAF with interim stops at FWA and the South Bend International Airport (SBN), South Bend, Indiana.

According to the flight instructor's statement, the flight was conducted as part of the University's commercial flight training program. He stated that his student obtained a weather briefing before the flight and the weather was monitored throughout the flight. He stated that although the surface winds were high, the flight progressed from LAF to FWA uneventfully. He stated that during the landing approach the student applied crosswind correction with the right-wing low (into the wind), and the nose of the airplane pointed straight down the runway. The instructor stated that as the student flared for landing the airplane suddenly and severely rolled to the left. He believed that he heard the left wing scrape the runway. He stated that he assumed control of the airplane and simultaneously added full engine power and full right aileron control to attempt a go-around. He stated that the full right aileron input did little to correct the airplane's roll attitude and the wind pushed the airplane to the left of the runway. As the airplane's airspeed increased the instructor was able to level the wings and started to pitch up for the go-around. He stated that he did not feel as if he had the airplane "under control". When the airplane was about 25-50 feet above the ground it rolled right and nose low. The airplane then impacted the ground.

The student reported that they were landing on runway 5 at FWA and had planned to perform 4 touch and go landings at FWA before proceeding to SBN. The winds were strong and from the right of the airplane during final approach. He stated that he positioned the airplane in a crab to correct for the crosswind. The airplane remained in the crab and was stable until over the runway threshold. The final approach airspeed was increased appropriately for the gusts. Upon crossing over the runway numbers, he smoothly reduced power and transitioned the airplane into a slip, keeping the airplane banked into the wind and the rudder opposite to keep the nose aligned with the runway centerline. As he began the flare, a strong gust of wind pushed the airplane toward the left side of the runway. Because of this, a go around was initiated but the left wingtip struck the runway. He stated that the instructor took control of the airplane and the subsequent events happened too fast to remember.

The airplane was examined in a hangar after its recovery from the accident site. The airplane had significant damage to the forward fuselage. The engine was separated and only remained attached by control cabling and wiring. The top of the cowl exhibited crush damage to the right top. The windshield was broken out and the top of the windshield had mud and dirt stains. The firewall was crushed rearward into the cabin area. The right wing was broken about midspan and the tip shattered. The wing was broken in the rearward/downward direction. The left wing was broken about midspan and the leading edge was twisted downward. The pitot tube mounted on the lower surface of the left wing near the tip had its lower rear end partially ground off indicative of runway contact. The cabin section of the fuselage from about 2 feet aft of the firewall to the tail surfaces was intact. The tail surfaces were intact but the lower rudder fairing exhibited mud staining and crushing of the fairing indicative of ground contact. No preimpact structural defects were noted.

Flight control system continuity checks were performed with the following results:

Elevator cable continuity was confirmed from the elevator control surface forward to the elevator bellcrank located in the forward cabin console. Crushing damage to the forward fuselage resulted in the cables having slack. Due to the cable slack, movement of the yokes did not result in movement at the elevator; however, movement of the yoke did result in movement of the bellcrank to which the cables were attached.

Rudder control cable continuity was verified from the rudder forward to the rudder pedals. Crush damage resulted in slack in the rudder cables as well, however, pulling on the cables in the aft fuselage access resulted in both movement of the rudder surface and movement of the rudder pedals.

Aileron cable continuity was verified by pulling on the cables in the center console, which resulted in movement of the aileron actuators in the wings. The link between the aileron control surface and the actuator mounted on the rear spar was disconnected due to impact damage. This was true for both the right and left ailerons. Continuity from the yokes to the cables located in the center console was verified by movement of the yokes which resulted in movement of the cables in the center console.

Continuity of the left and right yokes was verified by movement of one yoke which resulted in like movement of the opposite side yoke.

Both flaps appeared equally deployed. The flap switch which was positioned at 50 percent.

No preimpact defects were noted with respect to the flight control system.

The airplane Cirrus Airframe Parachute System (CAPS) system had not been deployed. The safety pin for the activation handle was found in-place during the wreckage examination in the hangar. The opposite end of the cable which is normally attached to the rocket igniter had been previously disconnected after the accident. The CAPS solid propellant rocket motor, igniter, and reefing line cutters were removed from the airplane. The solid propellant rocket motor, the ignitor and reefing cutters were activated to dispose of potential hazards. 

Injuries To Persons

The flight instructor received lacerations to his hands and face, and other cuts and bruises. The student pilot received a fractured femur and various cuts and bruises. 

Flight Recorders

The accident airplane was equipped with a Recoverable Data Module (RDM), located in the tail of the airplane. The unit was undamaged and the recorded data was downloaded during the wreckage examination. 

Tests And Research

The RDM data that was downloaded during the on-scene examination consisted of comma-delimited text entries recorded at one second intervals. The data contained various flight parameters including but not limited to: aircraft attitude, position, speed, acceleration, engine parameters, etc. At 2156, the RDM recording showed several blocks of missing data with the engine RPM dropping to zero. This was consistent with an impact that stopped the engine. The last data string before impact recorded the airplane in a 56° right roll with the nose pitched up 12°, at an indicated airspeed (IAS) of 57 knots. Three seconds earlier the RDM recorded a roll angle of 17° left wing down, and a pitch attitude of 13° nose up. At the same time, the IAS was 55 knots and the flaps were deployed 100 percent. During this time, the engine speed was above 2,600 RPM, indicating that the engine was at full power during the attempted go-around. According to the RDM data, the aerodynamic stall warning had activated about 6 seconds before the impact.

According to the Pilot's Operating Handbook (POH) for the accident airplane, the aerodynamic stall speed at maximum gross weight, most rearward center of gravity, 0° of bank, and 100 percent flap deflection, was 59 knots IAS. The actual airplane loading was not determined during the investigation.

The POH also stated that landings had been demonstrated in direct crosswinds up to 20 knots. Based on the reported wind gusts at FWA, the airplane was landing with a 16.7 knot headwind component and a 19.9 knot crosswind component.

At the time of the accident the School of Aviation & Transportation Technology at Purdue University operated several SR-20 airplanes that were used for student training. The flight department had established wind and crosswind component limitations for all the aircraft that the university operated. For the SR-20 airplane used for dual instruction the wind limits were based on the reported winds and the wind direction relative to the runway heading. For wind 50° from runway heading the maximum wind was listed as 23 knots and was noted to include peak gusts. The wind limitations noted that if the wind began to exceed the limits that the airplane was to be returned to the airport for a full stop landing as soon as practical.
