Is there a Mil-Spec or other Standard for applying body filler?

Is there a Mil-Spec or other Standard for applying body filler?

Is there a Mil-Spec or other Standard for applying body filler?

(OP)
I am applying a general note for surface prep and application of body filler to an aircraft and I want to make sure I source the mil-spec or other applicable standard.

RE: Is there a Mil-Spec or other Standard for applying body filler?

(OP)
It is an AH-64E Apache Longbow

RE: Is there a Mil-Spec or other Standard for applying body filler?

Surely (?) Boeing specify something in the SRM, AMM, somewhere ?

or are you modifying an AH64 and don't have the manuals ??

another day in paradise, or is paradise one day closer ?

RE: Is there a Mil-Spec or other Standard for applying body filler?

(OP)
I am making modifications to the Horizontal Stabilator. Altering from Delta to Echo model. There are two panel access at the rear of the stabilator. The cut-out hole sizes are different shapes and will require body modification. This is a Part Task trainer simulator for the Apache Longbow E model. I do have an IETM but it will not apply for this modification.

RE: Is there a Mil-Spec or other Standard for applying body filler?

A training simulator ? presumably non-flying ? Do you Need MIL SPEC filler ??

I am sure that one of the aircraft TMs related to 'finishing' or minor structural repairs for dents... has this data... however I'm not sure there should be much need for depression fillers on an Army chopper undergoing routine refinishing... unless it looked like it flew thru a hail storm.

I suspect that there are folks at CCAD Corpus Christy TX or an Army field service engineer that has this knowledge/authority. Be careful the fillers are approved by the engineers.

In USAF 'T.O.s' this is typically covered under the topic "Weather Sealant and Aerodynamic Smoother Application" … which also fills/smooths gaps/seams/butt-joints... prior to painting.

We typically specify epoxy primer followed by a flexible filler such a MIL sealant... sanded or 'swiped smooth' [plastic squeegee, etc]... followed by over-coat of primer then top-coat.

Rigid fillers should be avoided since they may 'pop-loose [spall-off] in service' leaving an nasty 'hole' in the finish.

I was able to source the process through the IETM just as you said WKTaylor. Thanks for the help.
