Maintenance Lapse Identified as Initial Problem Leading to Lion Air Crash - WSJ
A Wall Street Journal article with a report of faulty 'airspeed sensor' calibration.
Crash investigators have concluded preliminarily that improper calibration of an airspeed sensor during maintenance touched off the sequence of events that led to October’s fatal Lion Air jetliner crash in Indonesia, according to people familiar with the details. The conclusion is subject to further analysis, these people said, but it is the firmest indication so far that a suspected maintenance lapse was the initial misstep that ended with the months-old Boeing Co. 737 MAX aircraft plunging into the Java Sea, killing all...

I thought it was an AoA vane (sensor), not pitot. Not that it matters much - bad data confuses "hidden" trim automation > results in strange aircraft behavior in supposedly manual flight > LOCA

I think you will find they meant that the AoA vane was incorrectly calibrated. That would certainly fit with the symptoms of the crash flight.

From the ATW article
Although government agencies typically fund search operations after a crash, the Indonesian Ministry of Transportation said in December it would only fund the investigation process while Lion Air would cover the cost of the CVR search.
Doesn't this development also call into question the integrity and diligence of the Indonesian MOT?
In Indonesia - the Govt doesn't have much money and so they can only pay so much - right now they're probably prioritizing the Krakatoa tsunami victims who are at least alive - in Indonesia there's always another disaster about to happen that requires funds...................

NTSC Continues Lion Air JT-610 CVR Search
http://mediaindonesia.com/read/detail/209161-knkt-lanjutkan-pencarian-cvr-lion-air-jt-610
(Google Chrome Translation)
"A KNKT source, speaking on condition of anonymity, told Reuters the team will have seven days using the ship KRI Spica to find the CVR..."
The National Transportation Safety Committee (NTSC) collaborates with the Navy's Hydrographic and Oceanographic Center (Pushidrosal) to return to search for cockpit voice recorders Lion Air JT-610 PK-LQP (CVR) which crashed in Tanjung Karawang waters some time ago.
Pushidrosal deployed KRI Spica-934 which departed from the Jakarta International Container Terminal (JICT) Pier 2, Tanjung Priok Port, Tuesday (1/8).
The departure of the Hydro-Oceanographic survey vessel under the guidance of the Pushidrosal was released by the Head of Regional Police Laksda TNI Harjo Susmoro and the Chair of the NTSC Soerjanto Tjahjono and the main officials of the two institutions.
Kapushidrosal in his written statement, said, the departure of KRI Spica-934 which has underwater equipment with advanced technology is to continue to look for the existence of CVR which until now has not been found with a complete tool such as Multibeam Echosounder (MBES), Sub Bottom Profiling (SBP) , Magnetometer, Side Scan Sonar, ADCP, and HIPAP equipment that can detect signals from the black box of Lion JT-610.
"In addition to the equipment, KRI Spica-934 also brought 55 crew members, 9 NTSC personnel, 18 Navy divers, and 6 Scientists," he said.
Meanwhile, the Chair of the NTSC Soerjanto Tjahjono said that the NTSC requested Pushidrosal's assistance with the latest equipment to look for the CVR's existence.
With all the power available, KRI Spica, which is commanded by Marine Lt. Col. (P) Hengky Iriawan, has time to look for the CVR Lion Air flight number JT-610 for 15 days, given the signal that CVR emits for 90 days.
At present the remaining remaining time is around 15 days left, since the Lion Air plane crashed in Karawang waters on October 29, 2018.
"We will focus on searching 5 x 5 meters wide, around the point where CVR is estimated. With all our efforts and prayers, we hope that the CVR can be found following the discovery of a flight data recorder (FDR) some time ago to complete the investigation into the cause. "The fall of Lion Air is certain," said Kapushidrosal. (OL-1)

An update in English:
Lion Air JT-610’s missing cockpit voice recorder found in waters near crash site
By Coconuts Jakarta Jan. 14, 2019
Indonesian authorities this morning found the cockpit voice recorder (CVR), a crucial missing piece in the investigation of Lion Air flight JT-610, which crashed into the Java Sea in October.
The CVR was found in waters off the coast of Karawang, West Java, near the plane’s crash site.
“The CVR of Lion Air JT-610 was found at 09:10 Jakarta time [0210Z - Airbubba], 8 meters below the seafloor, or 30 meters deep,” said Indonesian Navy Spokesman Colonel Liutenant Agung Nugroho this morning, as quoted by Detik. The CVR is now being transported by boat to an Indonesian Navy base in Pondok Dayung, North Jakarta.
Previously, search parties recovered the plane’s flight data recorder (FDR), which makes up one half of the “black box” — the other being the CVR — both of which may prove crucial in determining the cause of the crash.
The preliminary crash report from Indonesia’s transport safety agency suggested that pilots struggled to control the plane’s anti-stalling system immediately before the crash. Investigators also found that the Lion Air jet should have been grounded over a recurrent technical problem before its final journey, but have not settled on an official cause for the accident.
A lawsuit filed in Chicago blames Boeing for the deadly crash, claiming the manufacturer’s airplane was “unreasonably dangerous.”
The Boeing 737 Max jet — one of the world’s newest and most advanced commercial planes — plunged into the Java Sea on October 29 shortly after taking off from capital Jakarta to Pangkal Pinang city, killing all 189 on board. A final crash report is likely to be filed this year.
With additional reporting by AFP

Time and an timely manner
I am hoping the long salt water immersion didn't ruin the recording(s) and we get to see the transcripts in a timely manner.
Certainly think this will put the spotlight on the failing(s) in this devastating and sad accident.

A month or two in ~150 ft. deep salt water is a cake walk compared to what the latest generation of recorders are designed for.

Also assuming no beacon signal for weeks, it is pretty impressive that they found it.
I am interested to know how they went about the search.
