Narrative:

The fll control tower gave this pilot clearance for position and hold on runway 9L fll. As I pulled on the runway, I switched form the speaker to the headset position on the aircraft radio control panel. As I discovered later, the headset in the aircraft was nearly inaudible. After a longer than usual time in the position and hold on the runway, I faintly heard the tower give me clearance for takeoff. The tower must have been attempting to get me prior to my hearing them. While I departed the airport and turned to 060 degree heading as instructed, I realized that my delay on the runway had caused the tower to give a jet airliner on final behind me go around instructions, which he did. There was no threat to life or property, but it certainly was an unnecessary and expensive inconvenience to others. The cause of the incident is obviously my failure to check the headset prior to pulling on the runway. Upon arriving at my destination, I called the control tower and apologized for the incident. In the spirit of learning from your own mistakes, I will never change radio equipment again west/O having checked it thoroughly first.

Title: PLT OF SMA UNABLE TO HEAR CLEARLY ON HEADSET REMAINED IN TKOF POSITION ON THE RWY AND CAUSED A JET TO GO AROUND.

Narrative: THE FLL CTL TWR GAVE THIS PLT CLRNC FOR POS AND HOLD ON RWY 9L FLL. AS I PULLED ON THE RWY, I SWITCHED FORM THE SPEAKER TO THE HEADSET POS ON THE ACFT RADIO CTL PANEL. AS I DISCOVERED LATER, THE HEADSET IN THE ACFT WAS NEARLY INAUDIBLE. AFTER A LONGER THAN USUAL TIME IN THE POS AND HOLD ON THE RWY, I FAINTLY HEARD THE TWR GIVE ME CLRNC FOR TKOF. THE TWR MUST HAVE BEEN ATTEMPTING TO GET ME PRIOR TO MY HEARING THEM. WHILE I DEPARTED THE ARPT AND TURNED TO 060 DEG HDG AS INSTRUCTED, I REALIZED THAT MY DELAY ON THE RWY HAD CAUSED THE TWR TO GIVE A JET AIRLINER ON FINAL BEHIND ME GAR INSTRUCTIONS, WHICH HE DID. THERE WAS NO THREAT TO LIFE OR PROPERTY, BUT IT CERTAINLY WAS AN UNNECESSARY AND EXPENSIVE INCONVENIENCE TO OTHERS. THE CAUSE OF THE INCIDENT IS OBVIOUSLY MY FAILURE TO CHK THE HEADSET PRIOR TO PULLING ON THE RWY. UPON ARRIVING AT MY DEST, I CALLED THE CTL TWR AND APOLOGIZED FOR THE INCIDENT. IN THE SPIRIT OF LEARNING FROM YOUR OWN MISTAKES, I WILL NEVER CHANGE RADIO EQUIP AGAIN W/O HAVING CHKED IT THOROUGHLY FIRST.
