Narrative:

After flying a short distance north of ocean shores I started a descent from 4500 ft to 1200 ft engine gauges red normal and before descent carburetor heat was applied. While in descent student applied carburetor heat around 2000 ft. After leveling off at 1200 ft I applied carburetor heat with no indication of carburetor ice and all gauges read normal. Approximately 8 mins later engine failed abruptly. Went through emergency procedures, tried to restart engine 3 times, then decided to lower gear. Left engine failed then lost all hydraulics to lower gear. Used hand pump as specified in checklist. This pump system did not work as last resort used CO2 to lower gear. This also failed. Cut and feathered right engine before landing. Flaps up both mains ended up being down (had no indication of this except for a noticeable descent rate). Minor damage occurred to aircraft and thus an incident. This older twin aircraft was technically 'airworthy' but I will never compromise my intuition again as to whether an aircraft is airworthy or not. My intuition was that this aircraft was not airworthy and unfortunately I found out this feeling was true. Callback conversation with reporter revealed the following information. Reporter states concern about maintenance comes from conversations with other pilots. Aircraft was having problems and they did not seem to get fixed. Concern was mostly regarding hydraulic systems and why back up actions were not successful. 1 main gear locked, the other did not. FAA is investigating with reporter cooperation.

Title: ISTR PLT HAS ENG PROBLEM, THEN HYD PROBLEM. UNABLE TO EXTEND GEAR.

Narrative: AFTER FLYING A SHORT DISTANCE N OF OCEAN SHORES I STARTED A DSCNT FROM 4500 FT TO 1200 FT ENG GAUGES RED NORMAL AND BEFORE DSCNT CARB HEAT WAS APPLIED. WHILE IN DSCNT STUDENT APPLIED CARB HEAT AROUND 2000 FT. AFTER LEVELING OFF AT 1200 FT I APPLIED CARB HEAT WITH NO INDICATION OF CARB ICE AND ALL GAUGES READ NORMAL. APPROX 8 MINS LATER ENG FAILED ABRUPTLY. WENT THROUGH EMER PROCS, TRIED TO RESTART ENG 3 TIMES, THEN DECIDED TO LOWER GEAR. L ENG FAILED THEN LOST ALL HYDS TO LOWER GEAR. USED HAND PUMP AS SPECIFIED IN CHKLIST. THIS PUMP SYS DID NOT WORK AS LAST RESORT USED CO2 TO LOWER GEAR. THIS ALSO FAILED. CUT AND FEATHERED R ENG BEFORE LNDG. FLAPS UP BOTH MAINS ENDED UP BEING DOWN (HAD NO INDICATION OF THIS EXCEPT FOR A NOTICEABLE DSCNT RATE). MINOR DAMAGE OCCURRED TO ACFT AND THUS AN INCIDENT. THIS OLDER TWIN ACFT WAS TECHNICALLY 'AIRWORTHY' BUT I WILL NEVER COMPROMISE MY INTUITION AGAIN AS TO WHETHER AN ACFT IS AIRWORTHY OR NOT. MY INTUITION WAS THAT THIS ACFT WAS NOT AIRWORTHY AND UNFORTUNATELY I FOUND OUT THIS FEELING WAS TRUE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO. RPTR STATES CONCERN ABOUT MAINT COMES FROM CONVERSATIONS WITH OTHER PLTS. ACFT WAS HAVING PROBLEMS AND THEY DID NOT SEEM TO GET FIXED. CONCERN WAS MOSTLY REGARDING HYD SYSTEMS AND WHY BACK UP ACTIONS WERE NOT SUCCESSFUL. 1 MAIN GEAR LOCKED, THE OTHER DID NOT. FAA IS INVESTIGATING WITH RPTR COOPERATION.
