The landing gear on the Blue Islands ATR 42 plane failed to open after what was described by their airline as an "unspecified" mechanical failure.
The flight from Guernsey to Jersey, with 43 people on board crashed on the runway at about 08:30 BST.
No-one was injured, but flights have been suspended and the runway will remain closed until 14:30 BST. Passengers should check in as normal.
Jersey Airport spokesman Alan Donald said: "After touchdown, taxiing to its stand, there appeared to be a collapse of the undercarriage.
"At the moment all flights have been suspended and the runway closed, although the airport remains open.
"This was a full incident and all emergency services have attended.
"Fortunately there were no injuries."
Mr Donald said Saturday was one of the airport's busiest days and the advice to passengers was to check in as normal.
Blue Islands said there had been an unknown mechanical failure of the left hand handling gear.
A statement from the airline said: "We are currently working with AAIB to fully understand the facts of this unfortunate matter. A full investigation into the incident is under way.
"The incident was well managed and controlled by our crew who made sure the passengers were safely and quickly escorted from the aircraft."
An eyewitness at the airport said the plane was travelling down the runway, when it appeared to "to fall over".
