techs, if you’ve noticed visible light coming from the housing of a SDU-39/N
distress marker strobe light, you have a defective infrared red (IR) housing.
Inspect the light marker data plates for
NSN 6230-01-411-8535 or NSN 6230-01-
448-8340, and contract numbers SPO500-
98-D-2710 or SPO560-00-F-0162.
If you have any of these light markers,
request replacement housings by calling
Ann Schrage, Defense Supply Center
Philadelphia, at DSN 444-8103 or (215)
737-8103, or email her at
aschrage@dscp.dla.mil
.
Include in the request your unit, number
of replacement housings needed, unit
identification code, applicable NSN and a
mailing address with a POC.

rew chiefs, “look out below” might be
what you’ll holler if you lose the left
hand crew jettison door when your
Kiowa Warrior’s .50-cal gun is fired.
You can keep the door in place by per-
forming a thorough pre-flight inspection
first, like it says in TM 1-1520-248-10
and AMCOM maintenance information
message 98-MIM005.
Make sure the jettison rod extends
through the door hinge halves at least
1
⁄
2
inch and that the jettison release handle
safety wire is secure prior to .50-cal gun
firing missions.
If the safety wire is missing, or the
rod isn’t extended properly through the
hinge halves or the pin is not in place,
vibration will work the door mechanism
free. Then the door falls off the aircraft
as the gun fires.
Also be sure not to use the jettison
handle as a handhold or a handrest. If
that happens, you could accidently jetti-
son the door.
So don’t let another door bite the dust.
Pre-flight your bird before you take off
and inspect the door mechanism like it
says in TM 1-1520-248-PPM.
