Narrative:

I was holding at holey intersection (238 degree radial/21 DME off rbv VORTAC) on the RBV1 arrival into ewr. Center advised us we were outside the confines of the pattern. My first 3 orbits were normal. On my 4TH turn inbound on the 238 degree radial, I decreased my bank angle from 25 degrees to 20 degrees, in order to reintercept the inbound radial. When I started my turn outbound, I neglected to increase the angle back to 25 degrees, causing the aircraft to proceed outside the holding pattern. Center advised another carrier, who was holding over yardley VOR, to start an immediate turn to prevent a near miss (we never received a TCASII alert). I contribute my failure to fatigue. My day began in the early morning hours, with a report of XA20 local. Combine this with a 1 1/2 hour taxi in ewr, a 2 hour ground hold in msy, just to be rewarded with an extensive hold in frontal passage WX.

Title: AN ACR FO ATTRIBUTES HIS DEV FROM THE HOLDING PATTERN, CAUSING ANOTHER ACFT TO BE VECTORED AWAY, TO FATIGUE.

Narrative: I WAS HOLDING AT HOLEY INTXN (238 DEG RADIAL/21 DME OFF RBV VORTAC) ON THE RBV1 ARR INTO EWR. CTR ADVISED US WE WERE OUTSIDE THE CONFINES OF THE PATTERN. MY FIRST 3 ORBITS WERE NORMAL. ON MY 4TH TURN INBOUND ON THE 238 DEG RADIAL, I DECREASED MY BANK ANGLE FROM 25 DEGS TO 20 DEGS, IN ORDER TO REINTERCEPT THE INBOUND RADIAL. WHEN I STARTED MY TURN OUTBOUND, I NEGLECTED TO INCREASE THE ANGLE BACK TO 25 DEGS, CAUSING THE ACFT TO PROCEED OUTSIDE THE HOLDING PATTERN. CTR ADVISED ANOTHER CARRIER, WHO WAS HOLDING OVER YARDLEY VOR, TO START AN IMMEDIATE TURN TO PREVENT A NEAR MISS (WE NEVER RECEIVED A TCASII ALERT). I CONTRIBUTE MY FAILURE TO FATIGUE. MY DAY BEGAN IN THE EARLY MORNING HRS, WITH A RPT OF XA20 LCL. COMBINE THIS WITH A 1 1/2 HR TAXI IN EWR, A 2 HR GND HOLD IN MSY, JUST TO BE REWARDED WITH AN EXTENSIVE HOLD IN FRONTAL PASSAGE WX.
