Occam's, after "checking my dope"
From the NWA flight Ops webpage:
DC-9 Fleet status as of January 06
'03 '04 '05 '06 '07 '08 '09 10
165 158 142 141 136 128 124 119
Net change from 2003 to 2005 is a minus 23 aircraft.
REALITY
Feb 07 - 110 in service = NWA and ALPA wrong by 26 airplanes
End of 08 - 70-80 in service = NWA and ALPA wrong by 48-58 planes
but what is 500-600 pilots between friends...
I see where you're disconnecting...
The difference is the 24 aircraft "in storage" that are under the cycle limit. They are cycled into the system when one of the other hulls reaches a phase inspection point. The 24 hulls, less the 3 wrecked aircraft equals the total from the flight ops page for '07. [You cited 23 as the difference. The web site doesn't reflect the loss of the SuperTug mishap aircraft, which hasn't been officially struck]
Not to be pedantic, but the Ship numbers for the remaining DC-9's are: 9914, 9915, 9919, 9923, 9930, 9931, 9935, 9938, 9940, 9945, 9951, 9957, 9958, 9959, 9960, 9962, 9966, 9969, 9976, 9977, 9980, 9981, 9982, 9990. [Note: There are two other aircraft out-of-service, 9937, and 9942, but they are not RVSM at this time]
ALPA tracks which aircraft are "in-service" by insurance. Aircraft not
active aren't insured. The
Scope Scorecards ALPA publishes reflect the active aircraft and number of pilots in each category.
Here's the key detail: The current staffing level is based on the
active hulls (duh!). That's all we care about.
When the fleet plan was posted in '99, there was a detailed explanation of the "master plan" for preserving the DC-9 fleet by rotating aircraft. At the time, ALPA expressed a lot of skepticism about NWA's commitment to keeping the fleet up-to-snuff, and finding a replacement aircraft before the fleet timed-out.
Those are still legitimate concerns.
Your source might be making the same assumptions you did about the active DC-9 fleet. Did his numbers come from the
Scope Scorecard, or the Flight Ops site? As you might have guessed, I'm pretty interested in staffing and aircraft status. Let me know what you find out.
