Narrative:

The aircraft departed pellston, mi, and was departed. Pilot neglected to turn on transponder and I never radar idented the aircraft. Aircraft subsequently entered adjacent center's airspace without coordination. I believe a better scan of strips would have allowed me to catch this error. I also think that, had the pilot turned on his transponder, this never would have happened. This problem (pilots forgetting to turn on their xponders) has occurred more frequently over the last few yrs. A better scan and a warning to pilots about the need to verify their transponder is on are the only remedies I can think of.

Original NASA ASRS Text

Title: AN ACFT ENTERS ADJACENT AIRSPACE WITHOUT COORD.

Narrative: THE ACFT DEPARTED PELLSTON, MI, AND WAS DEPARTED. PLT NEGLECTED TO TURN ON XPONDER AND I NEVER RADAR IDENTED THE ACFT. ACFT SUBSEQUENTLY ENTERED ADJACENT CTR'S AIRSPACE WITHOUT COORD. I BELIEVE A BETTER SCAN OF STRIPS WOULD HAVE ALLOWED ME TO CATCH THIS ERROR. I ALSO THINK THAT, HAD THE PLT TURNED ON HIS XPONDER, THIS NEVER WOULD HAVE HAPPENED. THIS PROB (PLTS FORGETTING TO TURN ON THEIR XPONDERS) HAS OCCURRED MORE FREQUENTLY OVER THE LAST FEW YRS. A BETTER SCAN AND A WARNING TO PLTS ABOUT THE NEED TO VERIFY THEIR XPONDER IS ON ARE THE ONLY REMEDIES I CAN THINK OF.
