Narrative:

Cleared for right traffic to runway 30 to report right base. Heard tower clear navajo to follow my aircraft for runway 30. Preparing to turn right base to runway 30, I lifted right wing to clear turn. Noticed navajo converging on my flight path, immediately turned to left to avoid navajo and advised tower of conflict. Once again, tower cleared me to land runway 30 and advised navajo to follow. I then re-established my aircraft, inadvertently, for runway 33 and subsequently landed on runway 33 without clearance. Informed ground frequency of mistake and conflict with navajo. Personnel on ground frequency advised me there was no problem created from deviation, and further contact with control tower not necessary. Lessons learned were: necessity to clear area before any turns (especially high wing aircraft), making sure aircraft in trail have visually idented my aircraft. (Even so, may have different traffic of same type aircraft in sight.) if similar problem occurs, 'aviate, navigate, communicate.' ie, land on correct runway!

Original NASA ASRS Text

Title: PLT OF C172 HAS NMAC WITH NAVAJO WHICH WAS CLRED TO FOLLOW HIM ON APCH. PLT TAKES EVASIVE ACTION AND IS RECLRED TO LAND AHEAD OF THE NAVAJO. IN RESULTING CONFUSION HE LANDS ON WRONG RWY.

Narrative: CLRED FOR R TFC TO RWY 30 TO RPT R BASE. HEARD TWR CLR NAVAJO TO FOLLOW MY ACFT FOR RWY 30. PREPARING TO TURN R BASE TO RWY 30, I LIFTED R WING TO CLR TURN. NOTICED NAVAJO CONVERGING ON MY FLT PATH, IMMEDIATELY TURNED TO L TO AVOID NAVAJO AND ADVISED TWR OF CONFLICT. ONCE AGAIN, TWR CLRED ME TO LAND RWY 30 AND ADVISED NAVAJO TO FOLLOW. I THEN RE-ESTABLISHED MY ACFT, INADVERTENTLY, FOR RWY 33 AND SUBSEQUENTLY LANDED ON RWY 33 WITHOUT CLRNC. INFORMED GND FREQ OF MISTAKE AND CONFLICT WITH NAVAJO. PERSONNEL ON GND FREQ ADVISED ME THERE WAS NO PROB CREATED FROM DEV, AND FURTHER CONTACT WITH CTL TWR NOT NECESSARY. LESSONS LEARNED WERE: NECESSITY TO CLR AREA BEFORE ANY TURNS (ESPECIALLY HIGH WING ACFT), MAKING SURE ACFT IN TRAIL HAVE VISUALLY IDENTED MY ACFT. (EVEN SO, MAY HAVE DIFFERENT TFC OF SAME TYPE ACFT IN SIGHT.) IF SIMILAR PROB OCCURS, 'AVIATE, NAVIGATE, COMMUNICATE.' IE, LAND ON CORRECT RWY!
