The flight instructor's and pilot receiving instruction's failure to maintain clearance from a tree while taxiing.

Operated by WEST COAST CHARTERS INC (per NTSB report)

The airplane encountered extreme turbulence during descent.

Operated by WEST COAST CHARTERS INC (per NTSB report)

The flight crew's intentional operation with know deficiencies in the aircraft and their delay in aborting the takeoff when a no-takeoff warning was presented. An additional cause was the crew's failure to comply with flight manual procedures concerning stabilizer miscompare and no-takeoff indications. Contributing factors were the inoperative two-position horizontal stabilizer system due to the intermittent electrical connection at the aft fairing connector, as well as the runway approach lights impacted during the overrun.

EMPTY LEG MMSL TO KSDM IN ORDER TO CLEAR CUSTOMS. FLEW APPROACH INTO KSDM AT APPROXIMATELY1800L, LOST AIRPORT ENVIRONMENT WHILE CIRCLING, EXECUTED MISSED APPROACH, PROCEEDED TO OUR ALTERNATE KSAN. ON APPROACH INTO KSAN, UPON GEAR DOWN SELECTION, WE RECEIVED NOSE AND LEFT MAIN GEAR GREEN DOWN AND LOCKED ANNUNCIATIONS. RIGHT DOWN AND LOCKED ANNUNCIATOR REMAINED EXTINGUISHED WITH APPROACH FLAPS AND GEAR DOWN SELECTED. BEGAN DISCUSSIONS ON IF IT WAS A LIGHT BULB ISSUE OR AN ACTUAL GEAR UNSAFE CONDITION, INCLUDING PUSH TO TEST ON GEAR POSITION INDICATOR, WHICH ILLUMINATED ALL 3 LIGHTS. AT 1000’ AGL, SELECTED FLAPS FULL DOWN TRIGGERING GEAR HORN TO SOUND WITH INABILITY TO SILENCE AND RED GEAR HANDLE LIGHT TO ILLUMINATE. AT THAT POINT, EXECUTED GO AROUND IN ORDER TO TROUBLESHOOT SAFELY. WHILE RECEIVING DELAY VECTORS, CYCLED THE LANDING GEAR AGAIN RECEIVING THE SAME UNSAFE GEAR INDICATIONS AS PREVIOUS. AT THAT POINT WENT TO THE ABNORMAL PROCEDURES CHECKLIST AND FOLLOWED THE LANDING GEAR MANUAL EXTENSION CHECKLIST. UPON PUMPING THE MANUAL EXTENSION HANDLE, WE RECEIVED RIGHT SIDE GEAR DOWN AND LOCKED ANNUNCIATION AFTER 3-5 FULL PUMPS. WE THEN PROCEEDED INBOUND FOR THE APPROACH AND PRIOR TO LANDING PUMPED THE HANDLE AGAIN UNTIL MAX RESISTANCE WAS FELT PER THE CHECKLIST. LANDED SAFELY AND SHUT DOWN ON THE RUNWAY AS THE GEAR IS TO BE CONSIDERED UNSAFE PER THE CHECKLIST. WE PUMPED THE GEAR AGAIN PRIOR TO BEING TOWED OFF THE RUNWAY. CREW NEVER DECLARED AN EMERGENCY, ATC DECLARED THE EMERGENCY FOR THE AIRCRAFT. WE WERE MET ON THE RUNWAY BY AIRPORT FIRE AND POLICE AGENCIES READY TO RESPOND.

ON MARCH 11TH 2021 IN AIRCRAFT N49WC OPERATING AS WEST COAST (WCC) 49, WE DEPARTED KSEZ FROM RUNWAY 21 ON AN IFR FLIGHT PLAN. AFTER A ROUTINE DEPARTURE, WE RAN THE APPROPRIATE CLIMB CHECKLIST AND CONTACTED PHOENIX DEPARTURE. SHORTLY AFTER CONTACTING DEPARTURE, WE NOTICED A BURNING SMELL IN THE CABIN, THEN NOTICED VISIBLE SMOKE INSIDE THE CABIN. WE IMMEDIATELY DECLARED AN EMERGENCY WITH PHOENIX APPROACH. WE WERE STILL IN VMC, SO WE MADE AN IMMEDIATE TURN BACK TO KSEZ, TURNED OFF NONESSENTIAL ELECTRICAL EQUIPMENT AND THE BLEED AIR VALVES AND DUMPED THE CABIN PRESSURE TO HELP CLEAR THE SMOKE. WE THEN MADE A NORMAL LANDING ON RUNWAY 3. WE QUICKLY TAXIED TO THE RAMP AND EVACUATED THE AIRPLANE. UPON INSPECTION OF THE AIRPLANE, WE NOTICED OIL BOTH ON THE OUTSIDE THE LEFT (#1) ENGINE COWLING AND WITHIN THE LEFT ENGINE COWLING. SEDONA FIRE DEPARTMENT ARRIVED AFTER SEVERAL MINUTES, MADE A VISUAL INSPECTION OF THE AIRCRAFT AND USED A THERMAL TEMPERATURE READER TO INSPECT THE LEFT ENGINE AND DID NOT FIND ANY ABNORMAL READINGS. WE DID NOT NOTICE ANY VISIBLE FLAME OR FIRE WHILE IN FLIGHT OR ON THE GROUND.

CHECKED OUTSIDE AND COULD NOT SEE THE GEAR BUT BOTH SIDES OF THE AIRCRAFT THE LANDING GEAR DOORS WERE VISIBLE. WE SLOWED THE AIRCRAFT TO BELOW 184KTS AND ALSO NOTICED THE LANDING GEAR CIRCUIT BREAKER WAS POPPED. I ADVISED ATC THAT WE WERE HAVING A LANDING GEAR ISSUE AND WOULD KEEP THEM ADVISED. ABOUT 40 MILES FROM THE AIRPORT I MANUALLY LOWERED THE GEAR FOLLOWING THE CHECKLIST PROCEDURES. THE LANDING GEAR INDICATED IT WAS DOWN. I THEN DECLARED AN EMERGENCY BECAUSE THE CHECKLIST ADVISES THAT THE LANDING GEAR SHOULD BE CONSIDERED UNSAFE. A SUCCESSFUL LANDING WAS MADE AT SNA AND A SLOW EXIT WAS MADE AT THE HIGH SPEED TAXI WAY TO MINIMIZE THE AMOUNT OF TURNING. I SHUT THE AIRCRAFT DOWN AND WAS TOWED INTO MAINTENANCE.

ON SATURDAY 11/7/2020, DURING A SCHEDULED CHARTER FLIGHT FROM KSNA-KLAS, SHORTLY AFTER DEPARTURE N60WC DIVERTED/RETURNED TO KSNA DUE TO A CRACKED PILOT SIDE WINDSHIELD. NO EMERGENCY WAS DECLARED, AND THE AIRCRAFT SAFELY LANDED. ROOT CAUSE OF WINDSHIELD DAMAGE HAS BEEN DETERMINED TO BE FAILED HEATING ELEMENTS WITHIN THE WINDSHIELD. WE ARE CURRENTLY IN THE PROCESS OF REPLACING THE DAMAGED WINDSHIELD. SEE BELOW CREW REPORT. CLIFF AND I WERE FLYING 60WC FROM SNA-LAS TODAY NOV 7 AND WE EXPERIENCED A CRACKED PILOT SIDE WINDSHIELD INFLIGHT. CLIMBING THROUGH ROUGHLY 6,000FT THE TEMPERATURE WAS ABOUT 5 CELSIUS SO WE TURNED WINDSHIELD HEAT ON LOW. WE LEVELED AT 12,000FT WHERE THE TEMPERATURE WAS ABOUT -5 CELSIUS AND WE ACCELERATED TO ABOUT 220 KNOTS WHEN THE LEFT FORWARD WINDSHIELD CRACKED. NO ABNORMAL INDICATIONS WERE PRESENT WITH REGARDS TO PRESSURIZATION AND WE IMMEDIATELY INITIATED A DESCENT, SLOWED THE AIRCRAFT TO 150 KNOTS AND RETURNED TO SNA WITHOUT FURTHER INCIDENT.

Part: TUBE — LEAKING (RT ENGINE) · airframe 11,615 hrs · 9,196 cycles

SHORTLY AFTER DEPARTING, DIVERTED BACK TO DEPARTURE DUE TO A RIGHT BLEED AIR FAIL WARNING. THIS WAS A LIVE PART 135 FLIGHT, NO EMERGENCY WAS DECLARED, WHILE THE CREW LANDED SAFELY BACK AT AIRPORT. IN TROUBLESHOOTING THE DISCREPANCY TECHNICIANS FOUND A PIN HOLE THE PLASTIC/EVA TUBING RUN ALONG THE RIGHT ENGINE NACELLE. THIS SMALL PIN HOLE ALLOWED FOR ENOUGH AIR PRESSURE TO ESCAPE, CAUSING THE BLEED AIR WARNING SWITCH TO LOSE THE 2 PSI REQUIRED TO EXTINGUISH THE WARNING ANNUNCIATOR. THE TUBING WAS REPLACED AND A SATISFACTORY OPERATIONAL CHECK OF THE BLEED AIR WARNING SYSTEM HAS BEEN COMPLETED.

Part: EVA TUBE — DAMAGED (ZONE 100) · airframe 12,508 hrs · 10,596 cycles

REPORT FROM PILOT...I DEPARTED SNA IN N73WC UNDER THE CALL-SIGN "WEST COAST 73" (WCC73). WHILE CLIMBING THROUGH 17,000FT FOR FL270 I OBSERVED A RED MASTER WARNING LIGHT, ACCOMPANIED BY A "R BLEED FAIL" LIGHT. I PERFORMED THE MEMORY ITEM BY MOVING THE RIGHT BLEED AIR VALVE TO "PNEU & ENVIRO OFF" AND THEN RAN THE ASSOCIATED CHECKLIST FOR THAT FAILURE. THE CHECKLIST STATED THAT I WAS TO LIMIT OPERATION TO BELOW FL250. I THEN REQUESTED FL250 FROM LOS ANGELES CENTER. WITHIN A MINUTE OR TWO THE CABIN ALT HI MASTER WARNING WAS TRIGGERED ALONG WITH THE WARNING HORN (WHICH I SILENCED), INDICATING THAT THE CABIN ALTITUDE HAD EXCEEDED 10,000FT. I WAS AROUND FL200 AT THIS POINT AND WAS OBSERVING THE CABIN ALTITUDE SLOWLY CONTINUING TO INCREASE. WHEN IT REACHED 11,000FT I OPTED TO DESCEND TO FL180 TO SEE IF THAT WOULD HELP THE PRESSURIZATION CATCH UP AND GET THE CABIN ALTITUDE BELOW 10,000FT. AT FL180 THE PRESSURIZATION HELD STEADY AT A CABIN ALTITUDE OF 11,000FT, BUT WOULD NOT DECREASE. AT THIS POINT I DECIDED TO RETURN TO SNA TO SWAP AIRCRAFT. I INFORMED THE PASSENGERS, AND USED MY RADIO TO CALL ATLANTIC AVIATION AT SNA SO THEY COULD INFORM WEST COAST OPERATIONS THAT I WAS DIVERTING BACK TO SNA. I WAS ROUGHLY OVER ONT WHEN I INFORMED AIR TRAFFIC CONTROL THAT I WAS GOING TO RETURN TO SNA. NO EMERGENCY WAS DECLARED. I REQUESTED FURTHER DESCENT AND WAS GIVEN A NEW ALTITUDE OF 8000FT (IF MEMORY SERVES ME RIGHT).I WAS THEN GIVEN VECTORS BACK TO SNA AND THE REMAINDER OF THE FLIGHT WAS UNEVENTFUL... A PINHOLE WAS FOUND IN PART OF THE R/H BLEED AIR EVA TUBING RUN THAT LEADS TO THE BLEED AIR SWITCH. A LOSS OF PRESSURE TO THE SWITCH CAUSES THE BLEED AIR WARNING ANNUNCIATOR TO ILLUMINATE. ONCE THE EVA TUBE WAS REPLACED, PERFORMED SATISFACTORY GROUND CHECK OF BLEED AIR WARNING SYSTEM. ALSO PERFORMED SATISFACTORY GROUND PRESSURIZATION CHECKS.

SECONDS AFTER ROTATION, STARTED FEELING UNUSUAL VIBRATIONS, AND HEARING A LOUD RUMBLE. ALL ENGINE GAUGES INDICATED NORMAL AND EXPECTED VALUES, AND NO ANNUNCIATOR LIGHT CAME ON. SINCE THE PLANE WAS FLYING FINE, HOWEVER WITH A VERY SLIGHT PULL TO THE RIGHT, DECIDED TO CLIMB TO A FEW THOUSANDS FEET BEFORE PAYING MORE ATTENTION TO IT. AFTER COMPLETING THE AFTER TAKEOFF CHECKLIST, ASKED THE COPILOT IF HE SAW ANYTHING ON THE RIGHT SIDE. REPORTED THAT AN UPPER WING PANEL HAD PARTIALLY COME OFF AND WAS FLAPPING AROUND. CONSIDERING THE POSSIBILITY THAT THE PANEL COULD COME OFF AND CAUSE ADDITIONAL DAMAGE TO THE FRAME, I TOLD MY COPILOT TO DECLARE AN EMERGENCY, AND WE STARTED HEADING BACK FOR A LANDING AT KSNA. WE DID NOT START FEELING OR HEARING THE EFFECTS OF THE DAMAGED PANEL UNTIL AFTER ROTATION, BUT I HAD NO WAY TO TELL WHETHER THE PANEL MAY HAVE BEEN DAMAGED BEFORE THE ACTUAL ROTATION, DURING THE TAKEOFF ROLL. NOTHING WAS NOTICED DURING THE PREFLIGHT INSPECTION.
