In the January issue of Flying magazine, there's a neat article about the Air National Guard (ANG) in Ohio. The writer explains his experience when flying in a KC-135R Stratotanker with the 121st Air Refueling Wing of the ANG of Ohio while on a mid-air refueling training mission over the eastern USA.
During the pre-flight inspections, it was noted that their KC-135R had 2 squawks/snags in the maintenance logs. The first squawk was in reference to the ADF, and the second was about vortex generators.
From the article ...............
"One vortex generator was missing from the bottom of the left horizontal stabilizer. It's okay to fly with two gone, and this was deferred to the next major maintenance."
My interpretation of the above sentence is that vortex generators (VG's) are on the KC-135's MEL list, and that the limit of missing VG's that can be deferred is only 2. If more than 2 VG's are noticed missing during a walk-around inspection, the aircraft will be grounded untill they're replaced. Have I understood this correctly?
So, my questions are .................
Do commercial airliners that use vortex generators on their wings, tails, flaps, etc, also have a set limit of VG's that can be missing in the airliner's MEL list? If the answer is yes, can someone give examples?
it would be interesting to learn that the need for such small objects could ground an airliner.
