Incident Overview
A pilot reported an encounter with wake turbulence during the landing phase of a flight. The pilot stated that while on final approach and cleared to land long, a Boeing 737 was cleared for an immediate takeoff. The pilot was instructed to make S-turns or other maneuvers as necessary to maintain separation.
Encounter and Recovery
As the pilot slowed for landing and descended to an altitude of approximately 10 to 20 feet above the runway, the aircraft encountered wake turbulence from the departing 737. The turbulence caused the aircraft to roll 60 to 70 degrees to the right and nose down. The pilot initiated recovery procedures and successfully returned the aircraft to a level attitude.
Landing
Following the recovery, the pilot landed the aircraft on the grass to the right of the designated runway. According to radar plot data, adequate spacing existed between the departing 737 and the Piper Seneca at the time of the incident.
Aircraft Information
The aircraft involved was a Piper Seneca. No specific registration or additional details were provided in the source.
