Nav light replacement bulb

[kortopates]

It would take more time than I have to really that well, but I'd start with 43.13 that says we have to follow the manufacturers maintenance manuals. for using anything else we need to have approved data, acceptable to the administrator, to allow us to use it, which is what STC process provides.

Here is some history.

Replacing any part with a part not listed in the manufacturers specification is considered an alteration.

FAR 43 Appendix A.

Paul,

does your IPC call for position light bulbs? Mine doesn't ('67F).

It calls for Position, Light p/n 800223 and -501 (Green) with not mentioning light bulbs at all.

How would you all proceed in this case?

Thank you.

Yeah, but he has an F. Your IPC is for C, D & E. they aren't always the same.

I am having trouble finding this replacement bulb for Green wingtip navigation light. Any suggestions?

Yours if you want it.

Just noticed both have a G21 marking on them. Not sure of the difference.

The point was they are spelled out in the WD. The other point was you need to know where to look, being the first step in maintenance. To be completely legal you must have your reference material at hand. At the airlines the feds would often walk up to us as we were working and demand to see the maintenance manual reference material we were using and it had better have that day's date on it. We made copies of the manual from a computer and they are date stamped.  Large aircraft manuals are updated on a daily basis.

My Maintenance Manual is dated in the 1970s . . . . Good thing I'm not an airline!

Thats a Grimes position bulb, P/N A1285-G-12 the Mooney P/N is 800223-501.  Whelen make a replaces bulb W1285SPG1

 

[cbarnes403]

I tried to quote cctsurf but guess it didn't post....

I do have a question, why can't you just replace the bulb with a cross referenced bulb.  we do the same thing for spark plugs, oil filters, wheel bearing.  

Guess all I'm saying is its the same part but different manufacture.

Whelen Chroma series LED. $115/ea. Probably THE brightest drop-in LED.

According to the Spruce web site, “FAA approval pending”

I found the red and green on Spruce ... is there a white for the tail? Please post a link if you have one. Thanks.

Yeah, I was looking at that as well. $115each is stupid for a light bulb but in a grand scheme of things drop in a bucket. I should be replacing them at my next annual.

I like how the grimes bulbs were taped off with masking tape and then spray painted to get the correct angles for viewing.   Wonder what GE bulb they used to do that with.

In other news, and for me just to be annoying.  Just because the picture of that you take of LEDs is brighter does not mean that they are really brighter.  It just means that the CCD in the camera you are using likes the temperature of the LEDs better than the incandescent bulbs.

Same as with the LED in a remote control.  hold the remote up to the camera to check and see if it is working.

 

[Raptor05121]

No white

Minor alteration.

They are noticeably brighter. Too early to pull out charts, etc. Nice to see on the ground, can easily see in daytime, etc.

Don't think you need an IA to sign off a light bulb replacement, just make a log book entry.

Looks great! I'd be happy with that improvement too. Any links to part numbers are source please?

Did you do the nav light globes too?

[Igor_U]

This looks like you replaced LED light bulb only, correct?

heck no the top one is 90 degrees out of alignment. that is going to cost you several knots in speed putting them in the slow way not aligned with the symmetry of the rudder and the rest of the plane.  It's what happens when you let armature mechanics work on the plane.

Good catch “Doc” ... I missed that. ... so used to most Wheelen products being PMA’d .... I’m holding off ordering them for now. The new FAA moves with lightning speed ... they should be approved any day now!!!

 

But a PMA is just an authorization to produce the part. I didn't think it said anything about the installation on any particular aircraft. I agree with others who have stated an A&P can sign it as a minor alteration. I don't see it as a major mod in any way.

Hehe.  Good luck getting someone to sign that off on a certified aircraft.

for those trying to follow the conversation and the doc references,  that may not have the illustrated parts catalog and maint manuals (including wiring/electrical): here are the sheets from my manuals:
