Narrative:

On approach into ord ILS approach to runway 27L, captain called for flaps 10 degrees, at approximately 1500 ft MSL, called flaps 15 degrees, no indication on flap position indicator. Captain called for flaps 25 degrees and again no indication. I then consulted the QRH. Referred to only applicable checklist (trailing edge flaps up landing). Captain landed aircraft safely and stopped plane with 3000 ft of runway remaining. Callback conversation with reporter revealed the following information: the reporter stated the cause of the flap extend problem was an electrical connector found disconnected on the flap control mechanism.

Original NASA ASRS Text

Title: A B737-200 ON APCH AT 1500 FT HAS TRAILING EDGE FLAP CTL FAILURE CAUSED BY A DISCONNECTED ELECTRICAL CONNECTOR ON THE FLAP CTL VALVE.

Narrative: ON APCH INTO ORD ILS APCH TO RWY 27L, CAPT CALLED FOR FLAPS 10 DEGS, AT APPROX 1500 FT MSL, CALLED FLAPS 15 DEGS, NO INDICATION ON FLAP POS INDICATOR. CAPT CALLED FOR FLAPS 25 DEGS AND AGAIN NO INDICATION. I THEN CONSULTED THE QRH. REFERRED TO ONLY APPLICABLE CHKLIST (TRAILING EDGE FLAPS UP LNDG). CAPT LANDED ACFT SAFELY AND STOPPED PLANE WITH 3000 FT OF RWY REMAINING. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE CAUSE OF THE FLAP EXTEND PROB WAS AN ELECTRICAL CONNECTOR FOUND DISCONNECTED ON THE FLAP CTL MECHANISM.
