Flight Crew Returned To Departure Airport
Aircraft; Human Factors
Had to return due to dual pressure controller failure; which resulted in an overweight landing. I coordinated with Dispatch; Station Ops and Maintenance for the overweight landing. After landing; I wrote up the pressurization issue; and then got caught up with multiple phone calls from Dispatch; Supervisor on Duty and [others]. At some point; while I was on the phone; Maintenance took the logbook to work the pressurization issue. I was informed that we were going to another aircraft; so we departed the aircraft. The previous aircraft was towed away; and we departed with the new aircraft. Once we got to cruise I reviewed [the paperwork] and realized that I hadn't made a logbook write up for the overweight landing. I sent an ACARS message to Dispatch to forward to Maintenance Control; about the missing write up. Upon landing; I called and talked to Maintenance Control so that the Maintenance Tech doing the inspection would document in logbook.
B737-700 Captain reported a dual pressure controller failure which resulted in a return to departure airport.
