Additional Participating Entity:
Federal Aviation Administration / Flight Standards District Office; Teterboro, New Jersey

Investigation Docket - National Transportation Safety Board:

Location: Farmingdale, NJ
Accident Number: ERA20CA113
Date & Time: 02/25/2020, 2356 EST
Registration: N135LR
Aircraft: Learjet 55
Aircraft Damage: Substantial
Defining Event: Runway excursion
Injuries: 5 None
Flight Conducted Under: Part 135: Air Taxi & Commuter - Non-scheduled


The pilot reported that he and the copilot were conducting an instrument approach to the runway in a business jet. He noted that the weather conditions included fog and mist. After touching down about 1,500 ft down the 7,300-ft-long runway, he engaged the thrust reversers and applied the brakes gradually because the runway was "slippery." As the airplane approached the end of the runway, he applied full braking, but the airplane departed the end of the runway and impacted a ditch, which resulted in the forward landing gear breaking and the airplane nosing down. The copilot corroborated the pilot's statement. The fuselage was substantially damaged. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The flight crew's failure to stop the airplane on the available runway, which was wet and resulted in the airplane impacting a ditch.

  1. Proper procedure when using anti-skid is to stand on them and let the system modulate the braking for maximum braking effect. Also, a 7500 foot runway, landing 1500 feet down the runway, left 6000 feet to stop. Just using the reversers would have been enough, not to mention the brakes. Something doesn't add up.

    1. And blaming it on the weather. I don't think the weather is type rated in the Learjet

  2. Weather is no excuse;
    Pilot did not allow for the conditions.
