Narrative:

On apr/xa/99 I received the following clearance, via telephone: cleared from gph to tys as filed, enter controled airspace heading 140 degrees to 3000 ft, FL230 in 10 mins, contact departure 119.0, squawk XXXX, void at XX23Z, current time XX21.5Z. I, as PIC, used poor judgement in accepting this clearance. Entering controled airspace, I was informed that I was late (6 mins) or past my void time. I was also asked to call upon landing. I received a very good lecture on using void times and clrncs! The first item that would decrease the likelihood of this happening to another pilot would be no clearance with a 2 min void time given over the telephone. Second, pilots need to know, ATC needs contact, radar or radio, with you within the void time. Just being airborne is not enough to justify requirements. This particular area, ATC radar pop-up around 1500 ft. Third, controllers should give aircraft a margin of error, especially when departing from an uncontrolled field. The back taxi and having to resecure the forward baggage door cost me time. I already had preflight complete and was ready. Waiting on another aircraft, back taxi, any number of variables can delay takeoff 4-5 mins. In my case, the back-taxi and baggage door problem. Finally, as PIC, I should not have accepted such a short void time, and from this time forward I will not accept one less than 15 mins. Everyone involved in this was very professional and polite. I learned something, and hopefully they did too.

Title: PLT OF PIPER CHEYENNE, PA31T, ENTERED CTLED AIRSPACE DURING DEP AFTER FLT PLAN VOID TIME.

Narrative: ON APR/XA/99 I RECEIVED THE FOLLOWING CLRNC, VIA TELEPHONE: CLRED FROM GPH TO TYS AS FILED, ENTER CTLED AIRSPACE HDG 140 DEGS TO 3000 FT, FL230 IN 10 MINS, CONTACT DEP 119.0, SQUAWK XXXX, VOID AT XX23Z, CURRENT TIME XX21.5Z. I, AS PIC, USED POOR JUDGEMENT IN ACCEPTING THIS CLRNC. ENTERING CTLED AIRSPACE, I WAS INFORMED THAT I WAS LATE (6 MINS) OR PAST MY VOID TIME. I WAS ALSO ASKED TO CALL UPON LNDG. I RECEIVED A VERY GOOD LECTURE ON USING VOID TIMES AND CLRNCS! THE FIRST ITEM THAT WOULD DECREASE THE LIKELIHOOD OF THIS HAPPENING TO ANOTHER PLT WOULD BE NO CLRNC WITH A 2 MIN VOID TIME GIVEN OVER THE TELEPHONE. SECOND, PLTS NEED TO KNOW, ATC NEEDS CONTACT, RADAR OR RADIO, WITH YOU WITHIN THE VOID TIME. JUST BEING AIRBORNE IS NOT ENOUGH TO JUSTIFY REQUIREMENTS. THIS PARTICULAR AREA, ATC RADAR POP-UP AROUND 1500 FT. THIRD, CTLRS SHOULD GIVE ACFT A MARGIN OF ERROR, ESPECIALLY WHEN DEPARTING FROM AN UNCTLED FIELD. THE BACK TAXI AND HAVING TO RESECURE THE FORWARD BAGGAGE DOOR COST ME TIME. I ALREADY HAD PREFLT COMPLETE AND WAS READY. WAITING ON ANOTHER ACFT, BACK TAXI, ANY NUMBER OF VARIABLES CAN DELAY TKOF 4-5 MINS. IN MY CASE, THE BACK-TAXI AND BAGGAGE DOOR PROB. FINALLY, AS PIC, I SHOULD NOT HAVE ACCEPTED SUCH A SHORT VOID TIME, AND FROM THIS TIME FORWARD I WILL NOT ACCEPT ONE LESS THAN 15 MINS. EVERYONE INVOLVED IN THIS WAS VERY PROFESSIONAL AND POLITE. I LEARNED SOMETHING, AND HOPEFULLY THEY DID TOO.
