Has anyone else experienced fire bottles thermally discharging due to high ambient temps? We've seen a few cargo bottles blow their thermal relief plugs over the past month due to high ambient temps. Is the CRJ-200 the only aircraft that has this problem in the summer? The high heat level in the APU bay is just too much for the bottles to withstand.

YV had a problem with that on the CRJ2. A policy was instituted prohibiting running the APU on the ground because of that issure. Supposedly air and power would "automatically" be connected upon arrival. It didn't happen. We would sit and sweat with no air for 10 minutes in PHX with a 110 OAT. Still no air so started the APU. That great idea lasted about a month.
