[Mark Hudgens]

Has any one changed the landing and taxi lights on the tr182? I have 100w
28 volt lamps on my 82 tr182 and have temp replaced with 250W......any

This will cause the Landing light circuit breker to blow at the most
innoportune time!!!

I had this happen to me on our CAP TR182. I was flying a search dog
team to Escalante, UT at 3:00am. 1L7 has a black hole approach.
(http://www.airnav.com/airport/1L7). The landing lights went off
on short final, and I landed using only the runway edge marker lights.

Come to find out that some idiot had replaced the specified 100W
landing lamp with a 250 Watter.

My recollection (but it has been a few years) is that when the breaker
tripped it took out both the landing light and taxi light...
If you do the math, the current drawn by (250+100)/28 exceeds the 10A
rating of the breaker.

Yeah, don't. It's things like this that the FAA maintenance
regulations were set up for. Put in the right bulb and do yourself (and
plane) a favor.

To use it, you'd need to verify (both through the service manual
and visually to ensure no previous wiring modifications) the wire gauge
through the airframe is adequate for the larger capacity. Then, change
out the breaker for one of adequate capacity. Then, check to make sure
the switch can handle the larger current. Then, verify that with
everything one you don't exceed the 80% capacity of the alternator.

Of course, before you do any of this, you need to do a 337 and get
it approved from your friendly, neighborhood FSDO.
