Aircraft brings fish endlessly to shore (9)
I believe the answer is:
turboprop
'aircraft' is the definition.
(turboprop is a kind of aircraft)
'fish endlessly to shore' is the wordplay.
'fish' becomes 'turbot' (type of fish).
'endlessly' means to remove the last letter.
'to shore' becomes 'prop' (I've seen this in another clue).
'turbot' with its last letter removed is 'turbo'.
'turbo'+'prop'='TURBOPROP'
'brings' acts as a link.
(Other definitions for turboprop that I've seen before include "Pub torpor (anag) - type of aircraft" , "Type of aero engine" , "Jet engine with the turbine coupled to a propeller" , "It may still take off" , "Type of aircraft engine" .)
