I´m flying the 300 and I´m also the maintenance manager for that airplane.
It is a real fun airplane to fly, thats for sure. Loads of punch, great brakes etc.
Cabin is great,very roomy, but relatively noisy IMO.Main issue there is the door seal, which is not inflatable -you can move it in flight and see the sky...and the venting in the toilet that exhausts a lot of air into the battery compartment for heating. When you close the toilet door and the optional door between galley and cabin its way better. The Galley could be bigger, since we sometimes fly 7+ hrs...Baggage space is not as big as it should be IMO.
Systems are very straightforward,dark cockpit philosophy, great FMS es (Collins 5000),Proline 21 is absolutely the best you can get, CAT II capable.
We do have the berthable divan which is very much liked by our clients.
We have had (in roughly 350hrs) these snags:
1) Engine changed because of oil chip detected. (after 24hrs in service!!!) Comment of Honeywell: we never had ANY trouble in the oil system of that engine...the replacement was removed of an other airframe for....oil chips !
2) 2 PFD´s went blank
3) several standby instruments (BIG ISSUE: No stall protection withoutit, NOGO)
4) thrust reverser failed, new throttle quadrant solved that
5) faulty Fuel Hi LVL detector, R/H wing wouldn´t take any fuel...
6) spoiler computer defect
7) FMS CDU defect
8) L/H windshield leaky, exchanged
9) 2 brakes leaky, exchanged
10) lots of interior snags, such as seat pedestal covers coming off etc. Bombardier has an issue of quality, but they already changed to a new supplier
11) Paint: L/H engine inlet cowling lost most of it. Big areas along the fuselage that will come loose soon (you can feel it)
12) One airshow monitor went u/s
13) DVD player u/s
All in all I think Bombardier is trying hard but that airplane is complex maintenance wise, cause its a loose formation of flying computers and failure tracing can be difficult...
Rwy performance is absolutely fantastic for a real swept wing jet. Very low V-speeds. Fantastic brakes. Handles very easy, the hydraulic rudder, aileron and elevator are fantastic. The gear does a perfect job, even my landings are smooth...
It matches all numbers in the books, sometimes its even better. Longest trip I did was some 3380 NAM at .78 in the beginning and .82 towards the end, we landed with 1800 lbs remaining.
The field reps here in Europe do a good job, but Bombardier should make their homework. There is no sense in their propaganda regarding a filled sparepart warehouse in Frankfurt when EVERY single part we needed has to come from Montreal.
When we took delivery they said they realise that the market rates their support in not so good marks and that they want to improve...
I don´t really now the Hawker 4000, but Raytheon needed a real long long time to get it certified...I personally wouldn´t want that airplane before S/N 150 or so, but thats just my opinion.
