There's a recent TSB Canada report on a Navajo that landed on a road after the engines stopped
TSB Report .
... created a standard operating procedures (SOPs) document containing a normal procedures checklist for the PA-31-350. This checklist was compared to the one in the Pilots Operating Handbook (POH), ... which is published by the aircraft manufacturer. The investigation found differences between the 2 documents. Of note, in the POH descent checklist, there is a step to check that the fuel selectors are set to inboard. However, the air operator's normal procedures descent checklist did not include this item. Instead, the step to check that the fuel selectors are set to inboard was included in the before landing checklist.
The manufacturer's POH contains a caution note between the before takeoff and normal takeoff procedures that states, in part, "Outboard tanks are for coordinated level flight only and may never be used for takeoff."In the description of cruise flight, the POH contains the following statement: "If outboard cells are used during climbs, descents or prolonged uncoordinated level flight, power loss may result even if there is appreciable fuel remaining." ... Neither statement was reproduced in the ... normal procedures checklist document.
