Major Knirsch: The main assembly process is done
in three major sections : the cockpit forward fuselage
areas, the main fuselage area, and the tail section of
the aircraft. The major section parts are identified by
aircraft ship number during the process of building
up the aircraft. For example, F-15C number 150 had
its wings, main fuselage, tail section , and forward
fuselage being built all at the same time in different
sections of the main assembly area. As those parts
grow into the shape of an aircraft, they move forward
towards the main production area door. They reach a
splicing area as a complete whole section; there the
main three sections are spliced together. The sys-
tems are checked out to make sure the wiring is
good, and they move out the front door of the
building .
What occurs between the time the F-15 leaves the
assembly line and the acceptance flight?
Major Knirsch: During that time the aircraft moves
through a watershed hangar where the nose section
is subjected to quite a gush of water to make sure the
areas that hold electronic equipment are all water-
tight. Next, the F-15 avionics are installed. After this
black-box installation and checkout, the aircraft is
painted and readied for the flying status. Prior to the

HOW THEY DO IT
AT THE FACTORY
It's not unusual to see the effort down at 3. 7 flights
per aircraft or as high as 4.3. This seems to be the
normal rate for the last 2 years. The company just
about demands two flights out of the aircraft. After
their airworthiness flight where they speed-run the
aircraft out to V MAX, there's very little fuel left to
accomplish the lengthy radar checks that are neces-
sary. If everything works just absolutely perfectly and
a target is available in the right place at the right time,
they will be able to get it in one flight . But it's a pretty
comprehensive amount to do with the fuel available
after making a speed run.
What is the crew composition for acceptance
flights?
Major Knirsch: One pilot per aircraft. Every seventh
F-15 off the production line is a two-seat model. The
two-seat F-15D is flown on its acceptance flight with
both front and back aircrew members fully qualified.
We do integrate with contractor crewmembers. We
very often fly target for the company, and they fly
chase or target for us.
Where do your pilots come from? What's their
experience level?
Major Knirsch: The pilots come from the Tactical Air
Forces. When I first arrived in Saint Louis, I was
qualified in the F-4. I checked out in the F-15 locally,
as have two of my other pilots. Captain Skip Boles
came to us from Bitburg AB , Germany. He was the
first F-15 pilot to come from an operational squadron .
We try to keep a person in the office who is tactically
up to date so that we have a "realistic" acceptance
flight check. We are not test pilots, and don't neces-
sarily look for a test-pilot background for the job here
in Saint Louis. We accept the aircraft for the govern-
ment, and we like to consider ourselves tactically
oriented .
What are the weather limitations you operate under
for the F-15 flights?
Major Knirsch: We look for 1,500-foot cei ling and 3
miles visibility- basic VFR. We will not fly a first flight

engines unless we can get back to Lambert VFR . We

10 JUNE 1982
Do you provide any special services to delivery
pilots?
Major Knirsch: We sure do. Each delivery pilot that
comes in to pick up his aircraft gets a face-to-face
briefing from one of our AFPRO flight acceptance
pilots. This briefing includes local area procedures
and safety hazards, his particular aircraft and main-
tenance problems we 've had with it, and how those
problems were resolved. The pilot usually gets a tour
through the factory to see how his Eagle jet is put
together. We assure that we have a supervisor of
flying (SOF) available for his takeoff so that if he has
any questions about his aircraft or problems once he
gets airborne , we can help.
How important is flying safety to your operations?
Major Knirsch: Safety to our operations is absolutely
paramount. We realize constantly that we are work-
ing with aircraft that could have some latent problem
in them from the manufacturing process , which could
be devastating to the pilot at any time. Each of my
pilots is highly qualified and has to be able to work
alone in an environment where he's the only decision
maker. We cannot accept anything less than a totally
safe operation . We cancel flights if all conditions do
not favor safety.
What is the most rewarding aspect of your job?
Major Knirsch: It's in the compliments we receive
from the field when they get their new airplane free of
"squawks." In the past we ran a string of squawk-free
deliveries that was up to 130 before we had one
minor squawk. That's a very satisfying part of the job,
when you consider the immense effort to produce an
aircraft. Other satisfactions are assuring that con-
tractual problems are solved .
We understand the U.S. Navy will take over the
management of AFPRO and begin to perform flight
acceptance on the F-15. Is that true?
Major Knirsch: The United States Navy is replacing
the Air Force's management function in contract
administration . We 're in the process of bring ing Navy
flyers up to speed in the acceptance flying of the F-
15 and F-18. At the present time I'm the govern-

Trailering. Keep in mind that the trailer, towing

Afterwards, we learned that the silver dollar panel

several reasons : a loose screw in the panel ; bent

power lawn mower accidents each year.
The commission offers these tips to do before
mowing to reduce chances of injury:
• Pick up all debris on the lawn .
• Check for hazards, especially near shrubs,
trees, and fences.
• Adjust the cutting height before starting the
mower.
• Fill the gas tank while the mower is still cool.
• If the lawn is wet, wait until it dries.
We have some suggestions to add to the list. First,
tune up the lawn mower. When the mower starts short shots
