Narrative:

On jun/xx/98, at approximately XX00 hours local time while PIC of a PA28-140 shortly after takeoff from cno (chino) I lost radio communications and became so preoccupied with correcting the problem that I lost track of my exact location in relationship to ral (riverside) class D airspace. The cause of the communications failure was rectified in-flight (it turned out the microphone jack had been kicked loose by a passenger) and communication was quickly established with ral's control tower. I had no set checklist for communications loss in-flight. I now realize that a checklist for communications failure should be part of every pilot's assortment of checklists. I have now created a checklist for communications failure which includes circling while attempting to correct the problem (this will prevent airspace violations) and the checklist includes checking the microphone jack along with other procedures. I believe that, in the future, being prepared in advance will prevent airspace violations and will make me a better and safer pilot.

Title: A PA24-140 PVT PLT LOSES COM ABILITY WHILE TRYING TO CALL RAL TWR. PERFORMS AN UNAUTH ENTRY INTO RAL CLASS D WHILE TROUBLESHOOTING HIS RADIO.

Narrative: ON JUN/XX/98, AT APPROX XX00 HRS LCL TIME WHILE PIC OF A PA28-140 SHORTLY AFTER TKOF FROM CNO (CHINO) I LOST RADIO COMS AND BECAME SO PREOCCUPIED WITH CORRECTING THE PROB THAT I LOST TRACK OF MY EXACT LOCATION IN RELATIONSHIP TO RAL (RIVERSIDE) CLASS D AIRSPACE. THE CAUSE OF THE COMS FAILURE WAS RECTIFIED INFLT (IT TURNED OUT THE MIKE JACK HAD BEEN KICKED LOOSE BY A PAX) AND COM WAS QUICKLY ESTABLISHED WITH RAL'S CTL TWR. I HAD NO SET CHKLIST FOR COMS LOSS INFLT. I NOW REALIZE THAT A CHKLIST FOR COMS FAILURE SHOULD BE PART OF EVERY PLT'S ASSORTMENT OF CHKLISTS. I HAVE NOW CREATED A CHKLIST FOR COMS FAILURE WHICH INCLUDES CIRCLING WHILE ATTEMPTING TO CORRECT THE PROB (THIS WILL PREVENT AIRSPACE VIOLATIONS) AND THE CHKLIST INCLUDES CHKING THE MIKE JACK ALONG WITH OTHER PROCS. I BELIEVE THAT, IN THE FUTURE, BEING PREPARED IN ADVANCE WILL PREVENT AIRSPACE VIOLATIONS AND WILL MAKE ME A BETTER AND SAFER PLT.
