Have any airliners successfully landed on a runway after striking a tree?
Searching through the Aviation Herald database for incidences with the word tree, I found 3 cases:

An Eagle Air Let L410 contacted a tree during departure from Lankien in South Sudan. The right wing tip was damaged, but the aircraft continued to its destination, where the wing tip was repaired:


A China Eastern Airbus A320 contacted trees during a go-around at Wenzhou after losing visual contact with the airport during approach. The damages were only found after landing though:

A post flight inspection found scratch marks on the right main landing gear, slats and flaps of right main wing and the inlet of the right hand engine (CFM-56). An inspection of the right hand engine revaled damage (dents sized up to 0.2 mm) to all 36 fan blades, scratch marks (13cm in length) at and twigs embedded in the oil discharge.

Due to the late decision by the crew the right hand wing, right hand engine and right hand main gear impacted and clipped treetops outside the airport perimeter.


A Cebu Pacific Airbus A320 came in contact with trees, but the damage was also only found after landing:

a subsequent pilot inspection found branches and leaves embedded in the right hand main gear, the right main gear was leaking hydraulic fluid. The occurrence was rated a serious incident and is being investigated by Philippines's AIB.
