2 October 1996 - Aeroperu 603

Flight 603, a B757 with registration N52AW, took off from Lima runway 15 at 12.42h am for a flight to Santiago. Five minutes after take-off the crew reported problems with their instruments and stated they wanted to return to the airport.

During the initial climb, the airspeed and altitude indications were too low. In calm winds, the windshear warning suddenly sounded. The aircraft climbed to FL130, before a return to Lima was initiated. While returning, the captain's airspeed and altitude indications were too high, causing an overspeed warning. At the same time, the co-pilot's airspeed indications were too low, triggering the stick shaker.

The aircraft kept descending and impacted the water with the left wing and no.1 engine at a 10 degrees angle, at a speed of 260kts. The aircraft pulled up to about 200ft and crashed inverted. The captain's airspeed indicated 450kts and altitude 9500ft.

Preliminary investigation results showed that the aircraft's three static ports on the left side were obstructed by masking tape. The tape had been applied before washing and polishing of the aircraft prior to the accident flight.

Cabin
(SOUND OF BEAT)

00:53:05 (12:48)
Copilot
I'LL FILL HERE THE DEPARTURE AND ARRIVAL... ILS RUNWAY 15... INSERT.
(This shows that the computers were active. Fernandez sets information needed for landing. Even when he knows that the air data has problems, Fernandez concentrates in landing procedures. Schreiber on the contrary, is concern with indicators)

00:53:14 (12:57)
Pilot
OK. YOURS IS SCREWED UP... THE AIR DATA.

00:53:17 (13:00)

SHIT, YEAH!

00:54:44 (14:27)
Copilot
IT'S GOING UP TO MUCH

00:54:48 (14:31)

AUTOPILOT DISCONNECTED, BETTER IF WE CONTROL IT ON BASICS, ISN'T IT?

00:54:57 (14:40)
Pilot
LET'S SEE THE TRIM

00:54:58 (14:41)
ATC Lima
ACCORDING TO PRESENTATION YOU ARE CROSSING RADIAL 230 FROM LIMA, DISTANCE WEST SOUTHWEST IS 37 MILES

00:55:07 (14:50)

(SOUND SIMILAR A ALARM DE PRECAUTION)

00:55:07 (14:50)
Copilot to ATC
CORRECT... WE WILL... WE HAVE PROBLEMS HERE FOR READING INSTRUMENTS, YOU WILL HAVE TO HELP US IN ALTITUDES AND SPEED IF POSSIBLE

00:55:17 (15:00)
ATC Lima
OK, ROGER

00:55:21 (15:04)
Copilot to ATC
UNTIL WE REACH THE LOCALIZER BEAM AND WE WILL NAVIGATE SOME 30 MILES NORTH OF THE LOCALIZER OF LIMA VOR TO CENTER IN THE ILS

00:55:30 (15:13)
Pilot
LET'S SEE... IF YOU SET THE ILS?

00:55:34 (15:17)
ATC Lima
AFFIRMATIVE, ROGER

00:55:38 (15:21)
Pilot
IT DOESN'T HAVE ALT HOLD... SET THE APPROACH, PLEASE

00:55:41 (15:24)
Copilot
I DID IT, I DID IT

00:55:42 (15:25)

THEN LET'S GO

00:55:44 (15:27)
Copilot
OK THE APPROACH... SET IT IN SMALL ONLY... SPEED, THIS IS THE SHIT THAT WILL... US

00:55:52 (15:35)

LET'S SEE, WE WILL TRY TO GO DOWN, OK WITH THIS COURSE AND... WHY IT DOESN'T APPEAR... AH... OK, OK

00:55:58 (15:41)
Copilot
NOW I HAVE...

00:56:00 (15:43)

I'LL TRY TO GO DOWN WITH EVERYTHING CUT... AH... OK.

00:56:09 (15:52)
Copilot
IT'S GOING UP

00:56:12 (15:55)
Pilot
LET'S GO DOWN TO TEN THOUSAND FEET... WHY DOES SPEED GETS SO HIGH? IS IT THE REAL SPEED?

00:56:21 (16:04)
Copilot
THIS IS WHAT WORRIES Æ ME... NO, I DON'T THINK SO...

00:56:28 (16:11)
Pilot
IT CAN'T BE... THEN... RUDDER RATIO, MACH TRIM... THEN IF THERE IS NOT THAT... MACH SPEED TRIM?

00:56:36 (16:19)
Copilot
NO, THERE IS NO MACH SPEED TRIM... I DON'T FIND... LET'S SEE, KEEP FLYING IT. IT WILL...

00:56:42 (16:25)
Pilot
YEAH

00:56:45 (16:28)
Copilot
IT'S CUT AND THE SPEED CONTINUES...

00:56:47 (16:30)
Copilot to ATC
CAN YOU TELL US THE SPEED, PLEASE?

00:56:49 (16:32)
ATC Lima
IT INDICATES 320

00:56:52 (16:35)
Pilot
WE HAVE 3500 BUT NO....

00:56:53 (16:36)
Copilot to ATC
CORRECT, WE HAVE ALL ENGINES CUT AND IT'S ACCELERATING... ACCELERATING.

00:56:59 (16:42)
ATC Lima
OK, ROGER

00:57:00 (16:43)
Copilot
TAKE THE SPEED BRAKE OUT.

00:57:02 (16:45)

NO... EH... NO. LET'S SEE, MAY BE... LET'S SEE, TAKE OUT...

00:57:05 (16:48)
Copilot
SPEED IS OK. ALL THREE INDICATOR ARE OK IN SPEED... FAST, FAST.

00:57:10 (16:53)
Cabin
(SOUND SIMILAR TO ALERT FOR 10 SECONDS)

00:57:12 (16:55)
Copilot
OVERSPEED... TAKE THEM OUT
(FDR analysis show that there was no overspeed. Overspeed alarm activated due to misinformation provided by air data computer depending on static ports)

00:57:18 (17:01)
Copilot
WARNING

00:57:22 (17:05)
Copilot
RUDDER RATIO
(Rudder ratio alarm activates again. Confusion increases with the overspeed alarm on when engines are cut down)

00:57:22 (17:05)
Pilot
IT CAN'T BE... RUDDER RATIO ONLY AND THERE IS RUDDER RATIO...THERE IS NOT AND IT DOESN'T DISCONNECT NOTHING

00:57:30 (17:13)
Copilot
ALL ENGINE INSTRUMENTS ARE OK, ALL ENGINE INSTRUMENTS ARE OK, SHIT!

00:57:34 (17:17)
Pilot
WHAT WOULD BE THE REAL SPEED?

00:57:38 (17:21)
Copilot
THIS ONE IS OK. THEY ARE OK THE SPEED... AIRSPEED

00:57:42 (17:25)
Pilot
BUT WITH ALL POWER CUT DOWN, IT CAN'T BE, WITH ALL CUT DOWN... THERE'S A PROBLEM WITH THE SOURCE INSTRUMENT

00:57:52 (17:35)
Copilot
INSTRUMENT SOURCE, SELECTOR, FLIGHT DIRECTOR, CENTER

00:57:58 (17:41)

WE WILL SET TWO FIFTY

00:58:37 (18:20)
ATC Lima
YOU ARE CROSSING THE 260 OF LIMA, AT 31 MILES WEST. FLIGHT LEVEL IS 100 PLUS SEVEN HUNDRED, AND APPROXIMATE SPEED IS 280 OVER THE GROUND

00:58:52 (18:35)
Pilot
YEAH... PERFECT

00:58:53 (18:36)
Copilot to ATC
YEAH, BUT WE HAVE AN INDICATION OF 350 KNOTS HERE

00:58:56 (18:39)
Pilot
LET'S PUT

00:58:58 (18:41)
ATC Lima
ROGER

00:59:04 (18:47)
Pilot
WHY ARE THESE MORE CLEAR?

00:59:08 (18:52)

(A TWO TONE OVER SPEED ALARM TRIGGERS AND WILL KEEP ON UNTIL THE END OF THE RECORDING)
00:59:10 (18:53)
Pilot
OVERSPEED

00:59:11 (18:54)
Pilot
FUCKING SHIT! I HAVE SPEED BRAKES. EVERYTHING HAS GONE, ALL INSTRUMENTS WENT TO SHIT EVERYTHING HAS GONE ALL OF THEM...
(Until that moment he has kept the air brakes activated, that's why he does not understand why speed has not decreased. But the truth is that the speed decreased even to a dangerous level. So 17 seconds after the overspeed warning and while it was on, the shaker alarm activates indicating stall warning)

00:59:27 (19:10)
Cabin
(SOUND OF STALL WARNING ALARM)

00:59:29 (19:12)

BUT WITH SPOILERS.. ALL OF THE...

00:59:51 (19:34)
ATC Lima
CORRECT, RESCUE HAS BEEN WARNED...

00:59:55 (19:38)
Copilot to ATC
WE REQUEST... IS THERE ANY AIRPLANE THAT CAN TAKE OFF TO RESCUE US?

01:00:05 (19:48)
Pilot
EH?... WAIT, NO, NO, NO, NO.

01:00:06 (19:49)
ATC Lima
YES, CORRECT, WE ARE GOING TO COORDINATE IMMEDIATELY, IT'S BEING COORDINATED IMMEDIATELY.

01:00:12 (19:55)
Copilot to ATC
ANY PLANE THAT CAN GUIDE US, AN AEROPERU THAT MAY BE AROUND? ...SOMEBODY?

01:00:17 (20:00)
Pilot
DON'T TELL HIM ANYTHING ABOUT THAT!

01:00:19 (20:02)
Copilot
YES, BECAUSE RIGHT NOW WE ARE STALLING...

01:00:21 (20:04)
ATC Lima
ATTENTION, WE HAVE A 707 THAT WILL DEPART TO PUDAHUEL (SCL), WE ARE TELLING HIM.

01:00:22 (20:05)
Pilot
WE ARE NOT STALLING! IT'S FICTITIOUS, IT'S FICTITIOUS.
(Pilot thinks that stall is not true. Schreiber is looking at the speedometers that indicate overspeed, which was wrong because the plane was loosing speed and air brakes were increasing lack of sustentation)

01:00:25 (20:08)
Copilot
NO! IF WE HAVE SHAKER HOW WOULD IT BE NOT...

01:00:27 (20:10)
Pilot
SHAKER... BUT IT IS... EH... BUT EVEN WITH SPEED BRAKES ON WE ARE MAINTAINING 9.500... WHY DO WE READ THE SAME..? I DON'T UNDERSTAND... POWER. WHAT POWER DO WE HAVE?
(Schreiber still believes in the altimeter when the stall alarm sounds. At that moment they check engine power that doesn't match with the 395 knots of indicated speed)
