FAA Field Approval For A Light Bulb?
Are you flippin kidding me? Thats the family-safe version of my response when a shop wouldnt install a Whelen PAR36 Parmetheus drop-in LED in a readers airplane without first lobbying FAA field approval. The aircraft, a first-gen Cirrus SR22, has a traditional incandescent landing/taxi lamp mounted in the nose bowl. Replacing it with the Whelen drop-in is a matter of accessing the lamp, unscrewing it from the mount, pulling off the connector and installing the new LED lamp in reverse order. Even a caveman could do that.
