Narrative:

At 400 ft I called for heading mode (takeoff). Just then, TCASII announced a TA +1. Looked at display to determine location. Target was so close, target was 'on us.' scanned from 12 O'clock position to 9 O'clock position. Piper was at 9 O'clock position and close enough to see color (white/blue stripe and numbers). I banked hard right, over 40 degrees, to clear area. On tower frequency, I asked who put the piper in our takeoff path! On departure control we discussed it. Departure control stated he saw it on radar. The controllers wanted to know if I was going to file 'papers.' they asked 3 times. Then he (departure control) gave me his name and phone number to discuss it when we returned from our trip. Supplemental information from acn 624539: we departed runway 8R and during standard turn to 140 degree heading, we got a TCASII TA 'traffic, traffic.' I could not see the traffic, but the captain did. Estimate 45 degree (right) bank to evade. We got a GPWS 'bank angle' twice. I finally got a visual of the traffic. It appeared to be a piper cherokee. He also appeared to be taking evasive action. I normally am very aware of any landing traffic but with my limited experience in the aircraft we trusted the tower's clearance while I completed normal checklists.

Title: NMAC BTWN A DEP B737 AND A XING, APCHING CHEROKEE AT 500 FT AGL 1 NM SE OF HNL.

Narrative: AT 400 FT I CALLED FOR HDG MODE (TKOF). JUST THEN, TCASII ANNOUNCED A TA +1. LOOKED AT DISPLAY TO DETERMINE LOCATION. TARGET WAS SO CLOSE, TARGET WAS 'ON US.' SCANNED FROM 12 O'CLOCK POS TO 9 O'CLOCK POS. PIPER WAS AT 9 O'CLOCK POS AND CLOSE ENOUGH TO SEE COLOR (WHITE/BLUE STRIPE AND NUMBERS). I BANKED HARD R, OVER 40 DEGS, TO CLR AREA. ON TWR FREQ, I ASKED WHO PUT THE PIPER IN OUR TKOF PATH! ON DEP CTL WE DISCUSSED IT. DEP CTL STATED HE SAW IT ON RADAR. THE CTLRS WANTED TO KNOW IF I WAS GOING TO FILE 'PAPERS.' THEY ASKED 3 TIMES. THEN HE (DEP CTL) GAVE ME HIS NAME AND PHONE NUMBER TO DISCUSS IT WHEN WE RETURNED FROM OUR TRIP. SUPPLEMENTAL INFO FROM ACN 624539: WE DEPARTED RWY 8R AND DURING STANDARD TURN TO 140 DEG HDG, WE GOT A TCASII TA 'TFC, TFC.' I COULD NOT SEE THE TFC, BUT THE CAPT DID. ESTIMATE 45 DEG (R) BANK TO EVADE. WE GOT A GPWS 'BANK ANGLE' TWICE. I FINALLY GOT A VISUAL OF THE TFC. IT APPEARED TO BE A PIPER CHEROKEE. HE ALSO APPEARED TO BE TAKING EVASIVE ACTION. I NORMALLY AM VERY AWARE OF ANY LNDG TFC BUT WITH MY LIMITED EXPERIENCE IN THE ACFT WE TRUSTED THE TWR'S CLRNC WHILE I COMPLETED NORMAL CHKLISTS.
