Narrative:

IFR flight ilm direct lbt, revenue flight. Both aircraft left ilm at the same time. Aircraft Y canceled IFR and advisories and proceeded 'VFR.' flight conditions were 4 mi, mist, haze, overcast at 4500 ft. Conditions at lbt were 2.5-3.0 mi visibility, broken at 800 ft, overcast at 4400 ft in light rain and mist. I was cleared (by fay approach) to 2000 ft to look for a visual approach! Traffic was called during descent, 'air carrier Y 3 O'clock position 1300 ft, descending.' I replied, 'no joy, IMC.' I broke out of clouds to see my 'VFR' 3 O'clock position traffic within 100 ft horizontally and vertically. Aircraft Y did not call (on CTAF 122.80) 10 mi/5 mi to traffic at lbt. I was monitoring both frequencys. Winds favored runway 23. I canceled IFR and descended to pattern altitude and then aircraft Y called 1 mi final for runway 31 (dogleg right base). After I stated my position, altitude, and intentions (ie, left base runway 23), aircraft Y canceled landing intentions on runway 31 and proceeded to follow my aircraft for left traffic on runway 23. The problem is that the 2 aircraft had the same estimated time of departure and estimated time of arrival.

Original NASA ASRS Text

Title: A PA32 SINGLE PLT RPTED AN NMAC WITH COMPANY ACFT IN LBT CLASS G AIRSPACE.

Narrative: IFR FLT ILM DIRECT LBT, REVENUE FLT. BOTH ACFT LEFT ILM AT THE SAME TIME. ACFT Y CANCELED IFR AND ADVISORIES AND PROCEEDED 'VFR.' FLT CONDITIONS WERE 4 MI, MIST, HAZE, OVCST AT 4500 FT. CONDITIONS AT LBT WERE 2.5-3.0 MI VISIBILITY, BROKEN AT 800 FT, OVCST AT 4400 FT IN LIGHT RAIN AND MIST. I WAS CLRED (BY FAY APCH) TO 2000 FT TO LOOK FOR A VISUAL APCH! TFC WAS CALLED DURING DSCNT, 'ACR Y 3 O'CLOCK POS 1300 FT, DSNDING.' I REPLIED, 'NO JOY, IMC.' I BROKE OUT OF CLOUDS TO SEE MY 'VFR' 3 O'CLOCK POS TFC WITHIN 100 FT HORIZLY AND VERTLY. ACFT Y DID NOT CALL (ON CTAF 122.80) 10 MI/5 MI TO TFC AT LBT. I WAS MONITORING BOTH FREQS. WINDS FAVORED RWY 23. I CANCELED IFR AND DSNDED TO PATTERN ALT AND THEN ACFT Y CALLED 1 MI FINAL FOR RWY 31 (DOGLEG R BASE). AFTER I STATED MY POS, ALT, AND INTENTIONS (IE, L BASE RWY 23), ACFT Y CANCELED LNDG INTENTIONS ON RWY 31 AND PROCEEDED TO FOLLOW MY ACFT FOR L TFC ON RWY 23. THE PROB IS THAT THE 2 ACFT HAD THE SAME ESTIMATED TIME OF DEP AND ESTIMATED TIME OF ARR.
