Location: Broomfield, CO
Accident Number: GAA17CA528
Date & Time: 09/09/2017, 1400 MDT
Registration: N89732
Aircraft: CESSNA 152
Aircraft Damage: Substantial
Defining Event: Loss of control in flight
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal

Analysis

The student pilot reported that, while landing in a "strong" crosswind, the airplane touched down on the runway centerline but then veered hard to the left. He attempted to correct by using rudder and aileron inputs, but he overcorrected, and the airplane veered sharply to the right and exited the runway. He applied full throttle to abort the landing; however, the airplane veered left across the runway, then continued off its left side. The airplane continued down an embankment, the nose impacted an "upslope" on the far side of a ditch, and the airplane came to rest inverted.

The airplane sustained substantial damage to the empennage and both wings.

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

The automated weather observation system located about 1 mile from the accident site reported, about 15 minutes before the accident, the wind was from 190° at 13 knots and that, about 15 minutes after the accident, the wind was from 210° at 17 knots, gusting to 21 knots. The student pilot landed on runway 12R.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The student pilot's failure to maintain directional control while landing in gusting crosswind conditions.

Findings

Aircraft
Directional control - Not attained/maintained (Cause)

Personnel issues
Aircraft control - Student pilot (Cause)

Environmental issues

Preventing Similar Accidents 

Stay Centered: Preventing Loss of Control During Landing

Loss of control during landing is one of the leading causes of general aviation accidents and is often attributed to operational issues. Although most loss of control during landing accidents do not result in serious injuries, they typically require extensive airplane repairs and may involve potential damage to nearby objects such as fences, signs, and lighting.

Often, wind plays a role in these accidents. Landing in a crosswind presents challenges for pilots of all experience levels. Other wind conditions, such as gusting wind, tailwind, variable wind, or wind shifts, can also interfere with pilots’ abilities to land the airplane and maintain directional control.

What can pilots do?

Evaluate your mental and physical fitness before each flight using the Federal Aviation Administration’s (FAA) “I'M SAFE Checklist." Being emotionally and physically ready will help you stay alert and potentially avoid common and preventable loss of control during landing accidents.

Check wind conditions and forecasts often. Take time during every approach briefing to fully understand the wind conditions. Use simple rules of thumb to help (for example, if the wind direction is 30 degrees off the runway heading, the crosswind component will be half of the total wind velocity).

Know your limitations and those of the airplane you are flying. Stay current and practice landings on different runways and during various wind conditions. If possible, practice with a flight instructor on board who can provide useful feedback and techniques for maintaining and improving your landing procedures.

Prepare early to perform a go around if the approach is not stabilized and does not go as planned or if you do not feel comfortable with the landing. Once you are airborne and stable again, you can decide to attempt to land again, reassess your landing runway, or land at an alternate airport. Incorporate go-around procedures into your recurrent training.

During landing, stay aligned with the centerline. Any misalignment reduces the time available to react if an unexpected event such as a wind gust or a tire blowout occurs.

Do not allow the airplane to touch down in a drift or in a crab. For airplanes with tricycle landing gear, do not allow the nosewheel to touch down first.

Maintain positive control of the airplane throughout the landing and be alert for directional control difficulties immediately upon and after touchdown. A loss of directional control can lead to a nose-over or ground loop, which can cause the airplane to tip or lean enough for the wing tip to contact the ground.

Stay mentally focused throughout the landing roll and taxi. During landing, avoid distractions, such as conversations with passengers or setting radio frequencies.

Interested in More Information?

The FAA’s “Airplane Flying Handbook” (FAA-H-8083-3B), chapter 8, “Approaches and Landings,” provides guidance about how to conduct crosswind approaches and landings and discusses maximum safe crosswind velocities. The handbook can be accessed from the FAA’s website (www.faa.gov).

The FAA Safety Team (FAASTeam) provides access to online training courses, seminars, and webinars as part of the FAA’s “WINGS—Pilot Proficiency Program.” This program includes targeted flight training designed to help pilots develop the knowledge and skills needed to achieve flight proficiency and to assess and mitigate the risks associated with the most common causes of accidents, including loss of directional control. The courses listed below can be accessed from the FAASTeam website (www.faasafety.gov).

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 student pilot reported that, while landing in a "strong" crosswind, the airplane touched down on the center line of the runway, but then veered hard to the left. He attempted to correct by using rudder and aileron inputs, but over corrected and the airplane veered sharply to the right and exited the runway. He applied full throttle to abort the landing; however, the airplane veered left across the runway, then continued off the left side of the runway.
