gbigs Posted June 16, 2015 Report Share Posted June 16, 2015 One of the gotchas on the landing light, at least on the CTLSi is the long wire has to be folded and tied to something with a zip-tie. In the case of the CLTSi is a fuel rail crossing the front. Two ties are needed, one to keep the wire bundle standing-off from the rail, the other to tie the folded wire up so it doesn't dangle on the engine. The long wire is needed to get the bottom cowling off and on where the light is mounted. Link to comment Share on other sites More sharing options...

FlyingMonkey Posted June 17, 2015 Report Share Posted June 17, 2015 What are the lumens of the new bulb? Link to comment Share on other sites More sharing options...
Jim Posted June 17, 2015 Report Share Posted June 17, 2015 It's about time. I designed, built, got an LOA, installed and got inspected my LED landing lights over 4 years ago. I wonder if they used my design. Link to comment Share on other sites More sharing options...
FlyingMonkey Posted June 17, 2015 Report Share Posted June 17, 2015 I thought that no LOA was needed to change the bulb, since the bulb doesn't have a FD Part Number... Is this new installation more than just a bulb swap? Link to comment Share on other sites More sharing options...
Runtoeat Posted June 17, 2015 Report Share Posted June 17, 2015 The FD factory LED light that I'm familiar with is a rectangular light. To retrofit this, the engine cowl must be modified. A portion is cut out and a "patch" that accepts the rectangular light is epoxied in. I'd have to say that one would have to make sure the cost required to buy the light and the patch and then the cost to modify would justify this.

The CTLS LED light is round, why would they not just use that?? Link to comment Share on other sites More sharing options...
FlyingMonkey Posted June 17, 2015 Report Share Posted June 17, 2015 I e-mailed Mat. This is a drop-in change to the SORAA lights that many are already using. $89 for the bulb (which is the same price I can find it online) and $50 for the MRA. The bulb is 600 lumens and 11.5W power draw. Again, the factory bulb has no FD part number, so technically I don't know if the MRA is legally needed...?

Andy, there is a part number and description for the lamp. C9997173 Alluminium Reflector Lamp 100W Halogen. Link to comment Share on other sites More sharing options...
Tom Baker Posted June 17, 2015 Author Report Share Posted June 17, 2015 These lamps are a drop in replacement as Andy pointed out. I spoke with Tom Peghiny about this light at Oshkosh last year. I followed up with a couple part numbers for bulbs that were listed here on the forum. They ordered some bulbs and did the testing to get the MRA.

FlyingMonkey Posted June 17, 2015 Report Share Posted June 17, 2015 Andy, there is a part number and description for the lamp. C9997173 Alluminium Reflector Lamp 100W Halogen. Thanks, I guess I was misinformed about the part #, I thought in another thread the LED lamp was listed as an allowable change because there was no FD part number for the halogen lamp. Is that part number the lamp manufacturer part number or an FD part number? Link to comment Share on other sites More sharing options...

Now you don't have to use the Flight Design part because they provide a specification 100W halogen lamp. You do need the MRA to use a part that doesn't meet the specifications.

Anticept Posted June 17, 2015 Report Share Posted June 17, 2015 As of today, I inquired and have received this response: Corey, Yes, there is a drop in replacement to change the halogen bulb to a LED. The LED light itself is $89.95 but you will need an MRA to make the change which is $50. If this is something you would like to do just let me know and I can get it going for you.

sandpiper Posted July 4, 2015 Report Share Posted July 4, 2015 An MRA for a drop in replacement? Why?? What am I missing? Link to comment Share on other sites More sharing options...
Anticept Posted July 4, 2015 Report Share Posted July 4, 2015 Permanent records. FD is supposed to keep records of all optional equipment on aircraft. Link to comment Share on other sites More sharing options...
Tom Baker Posted July 4, 2015 Author Report Share Posted July 4, 2015 An MRA for a drop in replacement? Why?? What am I missing? I am sure there are sparkplugs that are a drop in replacement, and I would bet you wouldn't use them without out the manufacturer's approval. My point is even though it is a drop in replacement it has an impact on, and is a major change to the electrical system. Of course the change is a positive one.

FredG Posted July 4, 2015 Report Share Posted July 4, 2015 "Positive" change to the electrical system. I see what you did there... Link to comment Share on other sites More sharing options...

Agreed, but the difference, in my mind at least, is this light has FD approval. Link to comment Share on other sites More sharing options...
Runtoeat Posted July 6, 2015 Report Share Posted July 6, 2015 Guess I'm behind on current landing lights. A while ago, there was a mod done to a CTSW where the rectangular CTLS LED light was installed which required modification of the cowl. Good to know a "drop in" hi intensity round LED is now approved. Link to comment Share on other sites More sharing options...
