Narrative:

Cleared for visual approach left downwind rw 22 avp GPWS terrain notification at 2800 feet MSL. Approximately; 45 degrees from the approach end of rw 22 in a 1 1/2 mile downwind.ATC cleared us for the visual approach left downwind runway 22. The crew had briefed the terrain; airport; and the visual approach rw 22 avp to be 'backed up' by the ILS rw 22 avp. We also briefed rw 22 is right traffic. I am aware of the terrain to the south of avp and noted on the chart the highest obstacle we would encounter in the downwind. I planned on turning base to rw 22 just outside the final approach fix. We also communicated that intention to tower as we were communicating with him and already cleared to land. As the terrain is hilly or 'mountainous' my plan was to descend form 4000 feet MSL to 2800 feet (the altitude of GS intercept at the FAF) in the downwind and turn the base while over a valley that placed me abeam the FAF. We were configured flaps 1 approximately 200 KIAS. As I initiated the turn to base we received a GPWS warning 'terrain; pull up'. I dis-engaged the auto pilot and added power and climbed to 3000 feet MSL. The GPWS annunciation extinguished and the flight continued on the approach and landing without further incident.[recommendations:]1. Insist on the right downwind rw 22 avp to keep clear of the terrain to the south of avp.2. Stay at 3500 feet MSL until established on the base leg rw 22 avp and clear of terrain; then descend to intercept the final approach course well outside of the FAF. This would necessitate communication and tower approval.3. Simulator training focusing on visual approaches into avp.
