From a performance, maintenance and passenger comfort standpoint, how does the Dash 8 rank? It is a beautiful aircraft but I don't know much about it.

Any Dash 8 pilots out there??

Thanks

I can not give you much information on the performance and maitenence aspects of the Dash8; however, being a frequent Dash 8 passenger, I can tell you that the Dash 8 is the most comfortable aircraft in the class. The cabin is not cramped like many turboprops and is also very quiet. As far as I can tell, the Dash 8 is also very stable.

Regards,
Jack Wheaton

Very over engineered and a little difficult to work on. Access is often blocked by miles of hydraulic tubing when you are trying to change components. Not as poorly designed as the Fairchild Merlin and Metro series, but close. Fantastic engines. Very reliable and easy to maintain. Weak areas seem to be the hydraulic systems (stainless steel lines are very susecptable to cracking, especially if exposed to vibration) and the landing gear. Sequence computer on the gear is easily confused and will cause the doors to close before the gear and so on. Also, used fiber optic sensors in the gear for positon and warning systems. Not a good idea where exposure to the elements is so frequent. Big blades on the props make them hard to keep in balance and they don't hold up well to rock nicks. Also, the aircraft has volumes and volumes of production and post-production mods that make ordering parts and troubleshooting certain systems a nightmare. It is almost impossible to determine the mod status of a particular aircraft without doing several hours of research. APU's seldom last more than 1000 hours. Tri-Wing screws are EVERYWHERE!!! CURSE THE NAZI SCREWS!!! Bonded fuselage is easily damaged, and when it is it can be down for days for what would be simple repairs on another aircraft. i.e. I know of a case where a ramp agent threw a suitcase into the bag well and took the airplane out of service for three weeks. I LOVE deHaviland aircraft, but this airplane reeks of NG Boeing. Simply put, it is over engineered and underbuilt, but not bad compared to others in its same size category. No one really builds a good 30 seat aircraft anymore.

I think it has the highest ascent rate of any turbo prop/jet, except maybe the Dash-7 but I am not sure. I would imagine it would be a better flight overall than on the old Dash-7

I work on them, and fly on them, and I think they are pretty good. Over engineered? Yes, but that's a nice thing when things go wrong, and you've got lots of backups. The hydraulic lines are crappy, but thats because the majority are aluminium, not stainless. Even dehav admits that was kinda dumb. The 400 is all stainless lines. The PSEU, (proximity sensor electronics unit), originally controlled gear sequence, but was modified years ago due to problems. Now it only provides position indication for the gear and all doors. Overall, a good a/c, and one that I'm comfortable flying in, in bad weather and mountainous country.
