Narrative:

Around XA10Z on dec/xx/96, I was cleared for the visual approach runway 15 at chs. While on short final I encountered wake turbulence and my airspeed dropped below 'blue line' and I remember being distraction by my airspeed and also wanting to clear the arrestor cable across runway 15 at chs to avoid the noise while crossing the cable and causing any alarm to the passenger. In so doing, I did not hear the approach controller instruct me to contact the tower for permissi on to land on runway 15. I do not think the controller remembered to do this, but also I do understand it is my responsibility to not land until I have a landing clearance. Nevertheless, I landed and spoiled my evening. To think I could have done anything so stupid! I am so grateful that it did not cause an accident. Corrective action: stay alert, beware of distrs, also applies to controller 'if' he did not instruct me to contact the tower for landing clearance. If so, he probably would have alerted me and the situation would not have happened. Also, a private pilot was riding in the copilot seat, and he also informed me that the controller did not hand me off to the tower for landing. Why he also did not tell me I did not have a landing clearance 'I can't understand.' he did not say anything, so he did not distract me. I can't believe I landed. I wish I knew the answer. I must stay more alert.

Original NASA ASRS Text

Title: SMT ACFT. DURING APCH, RPTR HIT TURB WHICH CAUSED AIRSPD DECAY. RPTR WAS ALSO FOCUSED ON LNDG BEYOND THE ARRESTER CABLE AND DISTRS CONTRIBUTED TO LNDG WITHOUT CLRNC FROM THE TWR.

Narrative: AROUND XA10Z ON DEC/XX/96, I WAS CLRED FOR THE VISUAL APCH RWY 15 AT CHS. WHILE ON SHORT FINAL I ENCOUNTERED WAKE TURB AND MY AIRSPD DROPPED BELOW 'BLUE LINE' AND I REMEMBER BEING DISTR BY MY AIRSPD AND ALSO WANTING TO CLR THE ARRESTOR CABLE ACROSS RWY 15 AT CHS TO AVOID THE NOISE WHILE XING THE CABLE AND CAUSING ANY ALARM TO THE PAX. IN SO DOING, I DID NOT HEAR THE APCH CTLR INSTRUCT ME TO CONTACT THE TWR FOR PERMISSI ON TO LAND ON RWY 15. I DO NOT THINK THE CTLR REMEMBERED TO DO THIS, BUT ALSO I DO UNDERSTAND IT IS MY RESPONSIBILITY TO NOT LAND UNTIL I HAVE A LNDG CLRNC. NEVERTHELESS, I LANDED AND SPOILED MY EVENING. TO THINK I COULD HAVE DONE ANYTHING SO STUPID! I AM SO GRATEFUL THAT IT DID NOT CAUSE AN ACCIDENT. CORRECTIVE ACTION: STAY ALERT, BEWARE OF DISTRS, ALSO APPLIES TO CTLR 'IF' HE DID NOT INSTRUCT ME TO CONTACT THE TWR FOR LNDG CLRNC. IF SO, HE PROBABLY WOULD HAVE ALERTED ME AND THE SIT WOULD NOT HAVE HAPPENED. ALSO, A PVT PLT WAS RIDING IN THE COPLT SEAT, AND HE ALSO INFORMED ME THAT THE CTLR DID NOT HAND ME OFF TO THE TWR FOR LNDG. WHY HE ALSO DID NOT TELL ME I DID NOT HAVE A LNDG CLRNC 'I CAN'T UNDERSTAND.' HE DID NOT SAY ANYTHING, SO HE DID NOT DISTRACT ME. I CAN'T BELIEVE I LANDED. I WISH I KNEW THE ANSWER. I MUST STAY MORE ALERT.

Small transport aircraft. During approach, reporter hit turbulence which caused airspeed decay. Reporter was also focused on landing beyond the arrester cable and distrs contributed to landing without clearance from the tower.
