NTSB Identification: GAA17CA192
14 CFR Part 91: General Aviation
Accident occurred Tuesday, March 07, 2017 in Laramie, WY
Probable Cause Approval Date: 06/07/2017
Aircraft: CIRRUS DESIGN CORP SR22, registration: N703TP
Injuries: 3 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot reported that, during the landing flare in gusting crosswind conditions, as the tires touched down, a wind gust lifted the airplane off the ground. The airplane drifted to the left off the runway centerline, and he added full power to initiate a go-around. The airplane suddenly banked “uncontrollably” to the left, and the left wing struck the ground, which resulted in the airplane coming to rest on its belly. The airplane sustained substantial damage to the fuselage and empennage.

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

A review of local weather from an automated weather observation station located on the airport revealed that, about the time of the accident, the wind was from 270° at 39 knots, gusting to 51 knots. The pilot landed on runway 21.

The Pilot’s Operating Handbook stated that, for crosswind landing:

Normal crosswind landings are made with full flaps. Avoid prolonged slips. After touchdown, hold a straight course with rudder and brakes as required. The maximum allowable crosswind velocity is dependent upon pilot capability as well as aircraft limitations. Operation in direct crosswinds of 21 knots has been demonstrated.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot’s decision to land with a crosswind that exceeded the airplane’s demonstrated capability, which resulted in the airplane banking left and the wing striking the ground.

The pilot reported that during the landing flare in gusty crosswind conditions, as the tires touched down a wind gust lifted the airplane back into the air. The airplane drifted to the left off the runway centerline and he added full power initiating a go-around. The airplane suddenly banked "uncontrollably" to the left, the left wing struck the ground, which resulted in the airplane coming to rest on its belly. The airplane sustained substantial damage to the fuselage and empennage.

Strong winds in Laramie and Albany County early this week caused problems for some on the land and in the air.

The University of Wyoming campus west of 15th Street experienced several power outages. Though they were all brief, some people working on desktop computers in campus computer labs and Coe Library experienced problems, said Chad Baldwin, UW director of institutional communication.

“They’ve been very brief, it only goes out for a second or two and comes back on, but it’s enough to bump your computer,” he said.

UW didn’t have any campus-wide class cancellations, but UW undergraduate Ana Marchese said she ran into problems. In addition to a class cancellation Monday, she said she lost some work for her math class because of outages.

“Most homework is done online for math classes, and so for my statistics homework, I lost a few problems due to power and Wi-Fi going off,” Marchese said. “The library was awful (Tuesday) because it went on and off every 15-20 minutes for a few hours.”

Rocky Mountain Power Media Team Representative Margaret Oler said the wind caused outages at UW, which overall affected about 2,000 customers in Laramie.

“When the wind’s blowing, (a line) comes too close to the line that it’s next to, so it causes that momentary outage, because the safety equipment cuts that circuit in order to minimize any damage that might occur if the line came down,” Oler said. “In this case, the line was sagging a little too low. Our guys were out there, they found the spot and they’ve repaired that. Hopefully, that will make (the momentary outages) go away.”

Areas west and northwest of Laramie saw the highest gusts during the wind event, said Richard Emanuel, meteorologist at the National Weather Service in Cheyenne. Gusts at Arlington were recorded at up to 80 mph.

“It’s been pretty strong all day,” he said.

At Laramie Regional Airport, where the strongest gusts were recorded at 63 mph, wind caused a Cirrus SR-22T to lose directional control as it was landing, said Cy Cass with the Laramie Fire Department.

“It sounds like the high winds caused his wings to impact the ground on the landing, and (the pilot) lost control, basically,” he said.

The LFD, Laramie Police Department, Albany County Sheriff’s Office, Wyoming Highway Patrol and airport fire responders all took the call, Cass said.

None of the three passengers in the aircraft were injured, he said. Some fuel spilled from the aircraft, but Cass said it was mitigated with a foam blanket from the LFD’s engine.

“We were pretty lucky today that everyone was OK and there was minimal damage to the plane,” he said.

Aside from the plane incident, Lt. Mike Simmons of the Wyoming Highway Patrol said problems persisted Monday-Tuesday, especially on a 25-mile stretch of I-80 west of Laramie.

“It has been really, really bad,” Simmons said.

Emanuel said winds should die down some today but could come up again later in the week going into the weekend.

Motorists considering travel plans should take caution and heed warnings from the Wyoming Department of Transportation when travel is hazardous, Simmons said.

“(Travelers) need to plan accordingly,” he said. “Look at www.wyoroad.info to plan your route when traveling across Wyoming.”
