Narrative:
Aircraft X was doing multiple IFR approaches at mwh. After completion of their first approach; they were given alternate missed approach instructions of 'turn right heading 100; climb and maintain 3000.' the helicopter came off of the airport on a heading of 100; climbing to 3000; and was radar identified. Once the aircraft reached the downwind area; I issued a right turn heading 140 to enter the downwind. The helicopter was climbing much slower than I was accustomed to and was only at 2700MSL when they were issued the turn; the MVA (minimum vectoring altitude) in this area is 3000MSL. By the time I had noticed this; they had already climbed to the MVA. The aircraft continued on the approach without incident. I issued the turn based on an expectation bias. Every other aircraft I have ever worked has been at the MVA prior to the downwind turn. There are no airspace or procedures that need to be changed.
