				XY-Wing 12 17 27 eliminating 2 in r9c4 solves the puzzle.
 
Also
 
A W-Wing 27 in r39c56 connected by a strong link in 7 in r6c56 eliminating 2 in r3c5 also solves it in one step. |

				A variation on the standard one step wing solution is a two stepper; a xyz-wing with a transport and a BUG+1.
 
 
xyz-wing 127 in r3c5
 
(1)r3c5 - (1=7)r6c5 - r6c6 = r3c6; r2c4<>7
 
(2)r3c5 - (2=7)r3c6; r2c4<>7
 
(7)r3c5; r2c4<>7
 
 
BUG+1 forces r3c5=7

				BUG+2 Either r2c4 or r3c5 must be 7 => r3c6 <> 7
 
 
(I'm new here - but enjoying these puzzles) |
