Narrative:

During climb from FL280 to FL300; master caution lights flickered on; then off. No annunciator lights were illuminated. Within 60 seconds; master caution lights flickered again; this time we saw that the r-hand CSD low oil pressure light flickered on then off in conjunction with the master caution. Checked in/rise temperatures. Rise temperature pegged at maximum deflection. Referred to flight manual and complied with irregular procedure for CSD low oil pressure/excessive rise temperature (disconnected r-hand CSD; confirmed disconnect; started APU and placed APU generator on line). Continued to destination and conducted an uneventful visual approach to landing at iad.

Title: B737-300 FLT CREW DISCONNECTS R CSD DUE TO LOW OIL PRESSURE.

Narrative: DURING CLB FROM FL280 TO FL300; MASTER CAUTION LIGHTS FLICKERED ON; THEN OFF. NO ANNUNCIATOR LIGHTS WERE ILLUMINATED. WITHIN 60 SECONDS; MASTER CAUTION LIGHTS FLICKERED AGAIN; THIS TIME WE SAW THAT THE R-HAND CSD LOW OIL PRESSURE LIGHT FLICKERED ON THEN OFF IN CONJUNCTION WITH THE MASTER CAUTION. CHKED IN/RISE TEMPS. RISE TEMP PEGGED AT MAX DEFLECTION. REFERRED TO FLT MANUAL AND COMPLIED WITH IRREGULAR PROC FOR CSD LOW OIL PRESSURE/EXCESSIVE RISE TEMP (DISCONNECTED R-HAND CSD; CONFIRMED DISCONNECT; STARTED APU AND PLACED APU GENERATOR ON LINE). CONTINUED TO DEST AND CONDUCTED AN UNEVENTFUL VISUAL APCH TO LNDG AT IAD.
