I heard that the maintenance at Keystone is pretty good as of now
Nothing to do with maintenance, more corporate culture and a history of shady operations. I know nothing about their maintenance, but even the best maintained bird in the world don't fly without fuel.
what, in your opinion singles out Keystone to be at a lower level than others that offer Navajo FO/ramp spots like sunwest and Wabusk
2000C1087 : The a/c appears to have impacted terrain with very little forward movement. The fuselage is intact and the occupants were able to exit the a/c on their own. The pilot was able to assist Emergency Services personnel by using a cell phone and providing directions based on sounds. The area where the a/c came to rest is completely enclosed by dense bush and trees and is not visible from a city street, about 300 meters to the north
2002C0623: KEE 208, a PA-31 Navajo with a pilot and six passengers, was arriving at Winnipeg International Airport after an IFR flight from Gunisao Lake, MB. The pilot reportedly was high on the ILS approach to Runway 13 and elected to overshoot. At some time during the missed approach, the pilot advised that he was having an engine problem and ATC provided him with vectors to land on Runway 25. The pilot shortly after, further advised ATC that the second engine had quit. Witnesses on the ground report hearing an engine backfiring as the Navajo passed overhead. The a/c descended into the northwest residential/industrial area of the city and hit the top of a city transit bus, knocked down a traffic light at the intersection of Logan and McPhillips Streets, struck a large delivery truck, then struck a smaller delivery van and impacted a paved street. The a/c came to rest on its left side on top of the left wing about 150 feet west of the intersection. The right wing and engine departed the a/c during the accident sequence. The 7 occupants were injured, with varying degrees of severity and all are in hospital. There were no injuries to anyone on the ground, although the two delivery vehicles struck on the ground were seriously damaged. The bus was only slightly damaged. Weather at the time of the occurrence was between 300 and 400 feet overcast. Four investigators from the TSB are on site. A Minister's Observer from System Safety has been assigned.

These in top of a general "I'm invincible" attitude to me shows a shady operator to stay away from, I stand by my original thoughts, and the thoughts i expressed in the last Keystone thread which was removed.
